  1. This makes me hungry
  2. CAN I BARROW UR BRAIN!!!?
  3. Eerr.. Bronze isn't a chemical reaction, it's an alloy. Just imagine putting some salt in water and mixing it in, it's not a chemical reaction, it's a solution. It's kind of the same with bronze. It's true that it had a great impact on history, but it's not a chemical reaction. Also, the crystallisation process used to make usable silicone is just that, a crystallisation process, not chemistry. However, there are metallurgic and crystallisation processes that rely on chemistry, the these two do not. But hey, it's ok to be.. well.. whatever : )
  4. LSD
  5. Hey, Can I get your autograph please?
  6. ?
  7. What about Gunpowder!
  8. Correction: There are trillions of chemical reactions in the body since there is a reaction in every cell.
  9. It didn't change history, but Greek fire is a pretty cool chemical reaction for its time. Especially considering that we aren't 100% sure what they used to make it.
  10. Before I watch I wanna guess. Salt, our atmosphere, the pool of elements that created life, gun powder, fire..... I give up now to watch.
  11. nuclear reaction, respiration and combustion . energy producing reactions
  12. I'd add the fission of a plutonium atom
  13. what about the reduction-oxidation reaction that introduced electricity to humanity ??
  14. Irony: demonstrating "drinkable water" with a clip of two glasses of wine containing deadly iocaine powder.
  15. gasoline
  16. Civilization IV yeah!
  17. 3:30 - Hey, put a SPOILERS sign before you show us an important scene from a must-watch (40 year old) movie (that's based on a 54 yo novel)!!!!
  18. Until you took a bite of that burger I watched. After that I accknowledge for being smart you just need a fancy channel name and some glasses.
  19. what was that one reaction that oblitarated hundreds of thousands of people in a matter of seconds i always seem to forget
  20. I forget what it is but the reaction required to make a lightbulb work
