NaOH and Aluminum BOIL and make EXPLOSIVE GAS!

Drop different surface area masses of Aluminum into NaOH (sodium hydroxide) solution and measure reaction rate with gases collected by balloons. Light the gases and on fire and see if they are combustible!
Along the way learn about how NaOH dissolves, how to calculate molarity, how aluminum reacts with Sodium Hydroxide, reaction rates, and combustion.
