We have been learning about the five kinds of chemical reactions: Synthesis, Decomposition, Single Replacement, Double Replacement, and the one all chemistry students love, Combustion. Most everyone is getting at least proficient at balancing these equations and identifying their type. It was time to blow something up.
They streamlined a 2 liter bottle and made it more aerodynamic. I built a rocket launcher out of 1/2 inch PVC and a charcoal grill spark igniter. They poured ethanol into their rocket and swished it around until it was filled with ethanol vapor. They then poured off the excess liquid and got the mass of the ethanol in the bottle by subtraction.
Now it was time to launch.
Here are the rocket scientists at work:
