I am currently a senior in high school. As a Chemistry student last year, I had the good fortune of learning from an excellent teacher; one who sparked an interest in me to continue with Chemistry this year. However, due to unfortunate circumstanses, this teacher left my school early this year, and while we have a replacement, there are still many aspects of the program that are lacking. For example, each year in the spring all the classes would do the "water rockets lab." It was a fun exercise that essentially used the combustion of H2 and O2 to propel the bulb of a pipet upwards of twenty meters. The two gases were created in separate test tubes fitted with small nozzles, and the bulb of the pipet was filled with water, than placed over the nozzles to allow the gas to displace the water. The gases within the bulb were then ignited. I have decided, out of respect for my previous teacher and with the consent of my current one, to perform the experiment with the current junior class. I know how to set up the equipment, and I know to use a reaction between Zinc and 3M HCl to create H2. However, I do not know how to create O2 effectively. I need a simple reaction, like that for H2, that can be performed in a test tube and uses somewhat readily available substances. Your assistance would be much appreciated, and I thank you for your time. ~Bryan
