To measure the sensitivity of AA, couldn't they try temperature? Say, store a dose in cryogenic condition then slowly raise the temperature until something happens?

How many times are fluorine and fluoride mentioned in this top ?  And they keep telling us how good it is to have " fluoride " in our water.

These people would come across a beautiful flower on the edge of a calm stream and think... "yea but can it be weaponized?" That violent state of mind should probably be studied with as much enthusiasm too no? because it's producing a being so toxic it has a violent reaction to everything it touches. Nature fights back in its own unique way though. Hopefully it continues to hide it's secrets for a more deserving species on this planet that isn't hell bent on destroying itself as a means of survival. Love your channel though.

Should have included Botulinum Toxin type H. Worlds deadliest substance, a red blood cells worth will kill you, or 2 nanograms

Great video! One question though. How can you smell anything almost instantly from a mile away? Do molecules disperse at the speed of sound?

try HBr saturated with bromine -- it tends to eat teflon and quartz. we were looking for the most corrosive material possible

Thioacetone is not actually a thiol. There's no sulfur-hydrogen bond. It's a thioketone.

I am actually ok with the smell of skunk. My local natural history museum has a bunch of different scents in vials for kids to sample, and skunk is one. I have good memories associated with the smell, so I kind of like it.
