Is your campfire trying to kill you? Exploding Rocks & Concrete
Ever heard of rocks exploding in a campfire? Can it really happen, and how dangerous is it? What happens if you spill molten metal on concrete? Today we will look at how and why concrete and rocks spall during a fire.

Hess's Law and Heats of Formation
How can we calculate the enthalpy change of a reaction without doing it? There are two easy ways! This is how we can make sure a reaction won't explode in our faces!

Copper acetate: Copper and Vinegar with H2O2.
Hydrogen peroxide acts as a catalyst oxidizing the copper. This is a very exothermic reaction and it can easily boil over if you don't keep an eye on it.

Exploding Arrows with compound bow! [Arrow filled with black powder, capped w/ shotgun primer]
This is our first attempt at exploding arrows, we probably used a half ounce of black powder in the arrow itself. It was a carbon arrow. We removed the tip and replaced it with a large shotgun primer. I saw these first in the anarchists...
