yall got some boring rockets, I build more fun stuff in my kitchen. it aint all about flow its about fuel/oxidizer ratio and compression and jet/nozzle size and for space faring rockets one must observe tsiolkovsky
When I saw this exact same experiment on another, more obscure, youtube channel I did think it was cool and I later saw an eposide of myth busters (first one on netflix) where they made a bigger one out of candle wax but it wasn't until watching this video with all the extra explanation that I had the idea to see if I can combine the two and drill out a candle on top of a jar with perhaps some battery acid as the catalyst (would love to get my hands on a medical oxygen condenser)
anyway, wish me luck as I really hope not to kill myself or burn the house down. ;-P
When theuy say: pure oxigen is highly reacting, what does it react with? for example would pure oxigen explode or burn if in contact with a flame? What the chemical reaction happening in the explosion?
You can also make a pulse jet with a mason jar by putting a small amount of pretty volatile fuel in it (I used methanol), poking a hole in the top, and lighting it. Very noisy and more exciting but not nearly as safe, especially since it tends to break, which, you know, spills hot jet fuel near a flame. It helps to put it in a pool of water though. Advice to anyone who wants to try this, it's important to get the hole in the top as round as possible. You can probably find pictures where people suspend a metal tube inside the jar but I've never tried it.
I feel like maybe a drop or two of liquid dish soap would have been beneficial, to prevent the liquid from potentially shooting through the hole. Too much of the peroxide or yeast might end up with the noodle or the floor wet.
Nice. A good addition to the experiment would be to burn a pasta without the added oxygen. Is the flame as high? Does the addition of oxygen do anything?
Myth Busters tried to build a hybrid rocket using a bunch of salamis (with a hole drilled down the center) stuffed into an aluminum tube, end to end, and nitrous oxide (if my memory is correct). Didn't work. blobs of salami broke loose and clogged up the hole.
So if you put the mason jar on a scale, you should see the wait increase, which will give you the thrust it's producing. After I wrote this I say a similar comment below. A bathroom scale would probably not be sensitive enough -- you'd need a kitchen wait scale set to grams.
Okay this just gave me a terrible idea. Put the hydrogen-peroxide and yeast in a potato cannon close it off, let pressure build up for a bit. Put powdered sugar or flour in the barrel and fire at a flame.
Don't do this, this is a very bad idea.
Not to be a pedant, but that's not how hybrid rockets work. Hybrids work by melting/entraining/subliming the fuel as the oxidizer is moving past, and combusting the two. The combustion moves from the center of the fuel grain out. This experiment basically just set a noodle on fire in an oxygen-rich environment.
Next you add the beryllium and thorium then mix with an anhydrous alcohol such as pentene and hover it through the vacuum cleaner make // make shift turbo pump mix a little LiO through another vacuum and Bush bash bosh you have a make shift jetpack
For anyine wondering whats the deal with Hank and Elon Musk, it went something like this:
Hank: You can agree with Elon that he is a job creator and also agree that he shouldn't have clapped back to a stranger in anger when he is a billionaire with millions of very passionate followers.
Elon: I think the person who attacked me on Twitter will survive somehow
Hank: Oof *sad emoji face*
Thats all, people in this comment section are blowing it up out of proportions.
The problem with using a kitchen scale to measure the thrust in this experiment as some have suggested is that the thrust force on the scale would be canceled out by the mass loss from the burning of the fuel and the release of the O2 from the peroxide.
I have a question for everyone in the comments who knows a lot about biology, I’m going into my señor year and want to have a bio project that involves generational breeding of aphids. Do you think 1 year is enough time to make the project results worth while. It’s about diet change and behavioral response
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
