Reactions

For science, we've been learning about reactions and how certain things effects reactions, such as heat, light, surface area, concentration, and of course catalysts, and what better catalyst is there than mentos in coke:

We also talked about exothermic and endothermic reactions. I wanted to do elephant toothpaste for this, but it was a major fail. BLAH! I need good high concentration hydrogen peroxide!!!

But we didn't have science the next week because it was COLD. Really cold. So cold, that vehicles didn't start and people would start coughing by just going outside.
