Jet+Boats+Cumulating+Activity

Concept involves design, testing and evauation of a rocket powered boat using an alcohol vapour reaction. The igniter is a BBQ lighter, you also need a hair dryer to warm up the boat containing the alcohol. For the launcher just use a one-hole stopper, push through and insulated wire (lamp wire is fine) and a piece of a coat hanger for support. The other end is attached to a BBQ igniter.

Variations to try include different alcohols or mixtures.

I measure the Power output with a Vernier Gas Pressure and Temperature Sensor on a test run (out of the water). from the graphical output students and determine gas volume produced using Ideal Gas Law but you can have them do it base on theoretical values and you don't need the Vernier setup.

Variation is to make rockets or cars, same analysis. For the rockets you can measure the height.
