1. Trayvon really needed one of those bullet proof hoodies.
2. Yes, but the point of a bulletproof vest isn't to magically and impossibly remove a bullet's momentum or prevent impulse, but rather to prevent a bullet from penetrating a person's body. You'll still feel the bullet's force, but it won't be concentrated into such a small area that it would pierce through your clothing and body and leave you bleeding to death. Obviously getting shot in the head in a bulletproof hoodie might still be fatal, but it'd be less damaging than actually getting shot.
3. In theory, the bullet will get reflected, just like the apple did, so it keeps some of it's kinetic energy instead of entering your head.
4. When I was like five I got the idea for non-Newtonian body armor. I actually went so far as to fill a plastic bag with cornstarch and water and shoot it. The corn starch reacts weirdly by first shattering, and then re-liquifying in midair (I go it on tape).
5. I call this stuff Jesus Juice. But not what you're thinking.... Because if you get enough of it and move quickly, you can walk on it. Me and my friend actually got the same idea about it stopping bullets so we filled one bottle with Jesus Juice(Oobleck, whatever), one with water, and one we left empty. We shot it with a .22 to see if it would stop the bullet, but all 3 bottles were penetrated and the bullet went straight through. But the bottles were damaged differently.
6. QI did an interesting thing with this stuff, where they put it on speakers and made it dance. Now I need new speakers.
7. Hank, what you're doing with scishow and everything else is wonderful. c: Please don't stop being awesome, okay?
8. :3 love and tolerate
9. playing with corn starch and water is possibly one of the funnest things i've ever done :D
10. you wont have a bullet in your head but itll feel like you got hit with a big rock
11. If someone gets 300k views in only five months ppls are gonna be jealous, that's just how stupid humans are. I love these vids although me thinks they are funnier than they're educational.
12. but even with the non-Newtonian fluid clothes stopping the bullet, the kinetic energy from the bullet has to be transferred somewhere, right? I mean, you get shot in the head with a bulletproof hoodie, all that energy will just be turned into blunt force trauma, right?
13. Hank, while my teacher was looking for a drug prevention video on YouTube I saw the thumbnail for this video. Almost reflexively I screamed out "HANK GREEN!" while my normally loud class decided to be dead silent. I got lots of weird looks, but at least I know I'm more knowledgeable for it.
14. This was one of my childhood dreams, I wanted to reverse engineer that plant that curls up when touched,and make it harden when touched instead and then apply it to motorbike clothing etc... :')
15. Shut up troll, this guy spends great amounts of time making videos (videos that are actually very interesting and entertaining) and you sit there doing nothing, and say its boring. Your boring asshole! I mean if your not into science, fine, but don't watch videos on a science related channel and judge the videos
16. you are boring
17. the apple teleported 0:45
18. we all need these ... cuz zimmerman's on the loose :O
19. Thank you for that, I love that guy.
20. like custard
21. Does this remind anyone else of that one Mythbusters episode???
22. Now I do. Thanks :)
23. it would suck if you actually got shot any way love your videos Hank hope mine can get as awesome as yours and Johns
24. is hank wearing a real bullet proof hoodie?
25. I was promised a bullet proof hoodie. I am dissapoint.
