Me (Joshua Judkins) doing general chemistry demonstrations for my Cornell CHEM 2070 lab students at the end of the semester Fall 2009. Demos (in order): Elephant toothpaste (catalytic (KI) decomposition of H2O2), Nylon synthesis, various objects in liquid nitrogen, luminol (chemiluminescence), and exploding sourpatch kid (decomposing KClO4 + carbohydrate)
