Spin art, simple homemade device /////Homemade Science with Bruce yeany
 
03:45
This simple device has seen a lot of use and is very popular with students. We use it as an example when exploring the concept of centrifugal force. There are several good demonstrations showing this concept, however,this centrifugal force can be misleading since it is not a real force. It is suggested that a good lesson accompany the use of these devices, otherwise students may end up with misconceptions of what is observed. Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylvania. I am currently in my 38th year of teaching. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself.. I also share and show some of these ideas at workshops, science conferences, or inservice presentations. Videos are shot with a Casio EXH20. Slow motion shots are either 3.5 or 7 times slower.

The misapplication of Newton's 3rd law as used in a children’s storybook and why it is wrong are shown along with some other variation suggested by viewers are tested in this latest video on the fan cart. I have intentionally tried to keep it’s explanation in simple terms for younger students since there are several higher level explanations already available from a variety of sources on the internet and here on youtube. Note on comments: I appreciate seeing comments positive or negative, and learn from helpful criticism. However, I am a middle school teacher and many of my students visit this site, I will remove comments that I feel are offensive or inappropriate.

***UPDATE*** https://youtu.be/jXEGpDsvKRw This is my home made perpetual motion machine. It started as a science fair project on renewable energy (powered by gravity). It is based on Bhaskara's wheel design which is a type of overbalanced wheel... very similar to several designs by Leonardo Da Vinci. I plan to add a small generator to it to generate electricity - free energy! My overbalanced wheel is a homemade perpetual motion machine that I intend on turning into a generator in order to produce free energy by taking advantage of the earth’s gravity. It is based off of an overbalanced wheel model designed by Bhaskara (an Indian mathematician). There are many other designed made by people such as; Leonardo da Vinci, Brownian, Gedanken, Honnecourt, Taccola, Zimara, and Villard. This machine may also be known as a; water mill, Persian water wheel, Villard’s wheel, Brownian ratchet, mass leverage machine, gravity wheel, Bhaskara’s wheel, or even a magic wheel.

Paper Saw Blades- paper cuts paper- Part 1- centrifugal force  //  Homemade Science with Bruce Yeany
 
06:47
Part one: Can a saw blade made out paper cut through a sheet paper? It can if it's spinning fast enough. Circles of paper are mounted onto a Dremel type tool and then are tested to see if they can cut paper, cardboard foam cups, even thin strips of wood. However, don't look to replace your steel saw blades with these anytime soon, these will disintegrate after a few uses, after all, they are just paper. The demonstration relies on the concept referred to as "centrifugal force". I would point out that this is a fictitious force. The behavior that it describes is real enough, however the words defining it are incorrect. the term "force" used with the word centrifugal is misleading and wrong, there is no force applied radially outwards. However, even though it is mislabeled, the term centrifugal force is used to describe the motion of the matter or an object moving radially outwards. This is what we observe here when the paper straightens out when spinning or the string on a grass trimmer becomes rigid as it spins and can be seen in all sorts of other examples and applications all well. It can be as simple as soaking a towel with water and spinning it over your head. The water drops move away from the towel outwards from the center of rotation ( centrifugal force). We can actually see similar results in the paint trails in the pictures at the endo of my spin art video. https://www.youtube.com/watch?v=FF0U7YIwm4M My preference would be to call it a centrifugal behavior. What we are seeing is a cause and effect. The centripetal force which causes the object to curve off of a straight is applied inwards towards the center of rotation. This inward force pulls against the inertia of the object and the effect or result is an outward movement even though there is no outward force. One further note on safety: I recognize that using the table saw without the guard down is dangerous, it was left up for visual purposes of making the video. My standard procedure is normally to use all safety measures available when using power tools. Also, as has been suggested, I would very strongly recommend that anyone attempting this experiment wear gloves as protection against paper cuts.

Centrifugal tray////Homemade science with Bruce Yeany
 
03:18
The classic demonstration of swinging a bucket over your head is taken up on notch by swinging a cup of water on a tray. Swing vertically or horizontally or a combination of both and the water remains in the cup to the "centrifugal force" acting on the cup. WHile this and other experiments demonstrating centrifugal force are a lot of fun, the concept can be misleading . A good lesson should accompany centrifugal force demonstrations to help clear up any misconceptions. Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylvania. I am currently in my 38th year of teaching. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself.. I also share and show some of these ideas at workshops, science conferences, or inservice presentations. Videos are shot with a Casio EXH20. Slow motion video clips are either 3.5 or 7 times slower.

Primitive Technology: Forge Blower
 
04:32
I invented the Bow Blower, a combination of the bow drill and forge blower to make a device that can force air into a fire while being easy to construct from commonly occurring natural materials using only primitive technology. I began by fanning a fire with a piece of bark to increase its temperature. It is this basic principle I improved on throughout the project. Next, I made a rotary fan from two pieces of bark that slot together at right angles to each other to form a simple 4 bladed paddle wheel about 20 cm in diameter and 5 cm tall. The blades of the fan were not angled and were designed only to throw air outwards away from the axle when spun. The rotor of the fan was made by splitting a stick two ways so it formed 4 prongs. The fan was then inserted into the prongs and the end lashed to hold it in place. Spinning the fan rotor back and forth between the palms of the hands fanned the fire. But only some of the wind generated by the fan reached the fire. The rest of it was blowing in other directions, effectively being wasted. So I built a fan housing from unfired clay to direct the air flow into the fire. This was basically an upturned pot with a hole in the top, a spout coming out of the side. The housing was about 25 cm wide and 8 cm tall. The hole in the top and the spout were both about 6 cm in diameter so that the air coming in roughly equalled the air coming out. The base of the fan rotor sat in a wooden socket placed in the ground to make it spin easier and the top of the rotor protruded from the hole in the top of the housing. Now when the fan spun, air entered the hole in the top of the housing and exited the spout in the side. Importantly, it doesn’t matter which way the fan spins, air always goes into the inlet and out the spout. Air is thrown out towards the walls of the housing and can only leave through the spout while the vacuum in the centre sucks new air into the housing through the inlet. A separate clay pipe called a tuyere was made to fit over the spout to direct air into the coals. This was done because the pipe that touches the fire can melt away so it’s better to make this part replaceable. Instead of making a large wheel and belt assembly to step up the speed of rotation, I opted for a 75 cm long bow. I made a frame to hold the rotor in place consisting of two stakes hammered into the ground with a socketed cross bar lashed on to hold the top of the rotor. I made bark fibre cordage and tied the end to a stick. I then looped the cord around the rotor and held the other end in the same hand holding the stick. I then pushed and pulled the bow causing the rotor to spin rapidly, forcing air into the fire. I made a simple mud furnace for the blower. Then I collected orange iron bacteria from the creek (iron oxide), mixed it with charcoal powder (carbon to reduce oxide to metal) and wood ash (flux to lower the melting point) and formed it into a cylindrical brick. I filled the furnace with charcoal, put the ore brick in and commenced firing. The ore brick melted and produced slag with tiny, 1mm sized specs of iron through it. My intent was not so much to make iron but to show that the furnace can reach a fairly high temperature using this blower. A taller furnace called a bloomery was generally used in ancient times to produce usable quantities of iron and consumed more charcoal, ore and labour. This device produces a blast of air with each stroke of the bow regardless of whether it is pushed or pulled. The bow makes it possible to operate the blower without using a complicated belt and wheel assembly used in traditional forge blowers. There is a brief pause at the end of each stroke where the fan stops to rotate in the other direction, but this is effectively no different to the intermittent blast of a double acting bellows of Europe or box bellows of Asia. The materials used (wood, bark, bark fibre and clay) are readily available on most continents. No leather, valves or precisely fitted piston gaskets are required as with other types of bellows. The cords for this device wear out often so a number of back up cords should be kept handy for quick replacement. In summary, this is an easy to make device that solves the problem of supplying forced combustion air required for high temperature furnaces and forges.

Toy Physics - Looping Pendulum /// Homemade Science with Bruce Yeany
 
04:00
This is a simple demonstration that can be used to impress your friends using a variety of materials. It also can make a nice investigation for a science fair project or a classroom demonstration. Students can test variables and determine the conditions for the best results. The use of small lights and a camera can help capture the beauty in the movement of the small weight as it arrests the movement of the larger weight as it falls. Or, one other use can be for amusement purposes by turning the demonstration into a game. One final note, the spiral path recorded in the pictures was described as an Archimedes spiral, it is actually an involute spiral. While they are very similar, there are subtile differences that can be explained and demonstrated by searching for definitions of these terms. Sorry for the mistake.

Pulled String Painting - Making Things From Them: A Bookmark
 
08:02
Hi. What to do with pulled string pictures once you've done them? Here's a Mackintosh Rose bookmark with one I'd made in the previous video. Hope it inspires you to look at your creations and find ways to make use of them. It would help me a lot if you could share my video's as it's obvious with the ones that have been shared that it does make a big difference! (Thank you to who has been helping me in this way! ) If you could share my work it will encourage us to continue to do good quality video production, and share my art in general. Also to do more in depth tutorials to pass on what I'm learning and re-discovering in art, plus more tips and tricks etc. We both put a lot of time and effort (not to mention expense) into wanting to help pass on my experience and to inspire/entertain you and come up with the odd invention too, just for you! So you taking just a minute to share what I'm sharing with you would be very encouraging and appreciated. Being dyslexic, social media sites are way beyond my abilities (and Mick simply doesn't have the time to help with this, too); so you'd be helping enormously if you could share. Thanks, Take care, Joanne.

Bicycle tuning  fork - physics of toys // Homemade Science with Bruce Yeany
 
04:14
The front fork off of a bicycle makes a nice addition to a tuning fork set. The frequency of this one is very low, about 54 Hz (vibrations per second). The sound of fork is very deep and the camera does not do a good job of picking it up but otherwise, it makes for an interesting piece of equipment. My students have found it to be entertaining to hold it against various surfaces, and in doing so it can be heard in other classrooms adjacent to mine.

How to Do a Basic Pole Spin | Pole Dancing

Watch more How to Do Pole Dancing Exercises videos: http://www.howcast.com/videos/509369-How-to-Do-a-Basic-Pole-Spin-Pole-Dancing So, you all have been doing searches for how to do a basic pole spin. A great one to start with, is an outside hook, double attitude. This is part of the krimen spin of vocabulary that we teach at New York Pole Dancing. The great thing about this spin is you actually get two spin impulses. So, you're going to start with your hand high, your feet close to the pole, your hips pulled away, and your half moon. You'll take three steps going for your basic outside hook set, reach away from the pole X, pivot to face the pole squaring off your hips and your shoulders. Grab with your outside hand underneath the inside in your baseball grip, swinging your outside leg for your first impulse, back to the side, finally hooking your heel onto the pole. That centrifugal force will make you spin. You'll pick up your inside leg. Your secondary spin impulse will come from that inside leg reaching all the way back behind you, with your knees bent, rotating outward from your hips. Your inside leg will be nearing your outside leg, and you take that all the way down to the ground.

How does the temperature affect water density, and how does the density affect the buoyant force that it can exert? This simple experiment that students can try for themselves can help to give them insight to the answers of these questions. Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylvania. I am currently in my 38th year of teaching. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself..

The basic concept of a reciprocating engine goes back about 300 years when first developed into a crude stream engine. the same basic principles are used in today's modern engine where expanding gas is used to drive a piston and a crank is used to convert the movement into rotary motion. This engine will run on the either the exhaust or vacuum of a shop vac, a vacuum sweeper, or compressed air. The stroke of the piston is 4 inches The movement of the cam to drive the air diverter is 2 inches 240 RPMs as shown... max is about 400 RPMs

Physics of Toys--Film canister cannon // Homemade Science with Bruce Yeany

A small cannon that fires a plastic film canister is one way to start a lesson off with a bang, well not really a bang, more like a pop. It shoots a film canister about 25 feet and is powered by just two drops of alcohol. The basic idea can be shown very simply, or with some time and effort can be built into a nice addition for an adult's homemade science toy demonstration piece. Warning: while the amount of fuel used is very small, it still produces a small explosion and flame, proper supervision and precautions are strongly recommended. NOT SUGGESTED FOR CHILDREN
