Science teacher Jacob Strickling is having a great time today (June 20) launching these little rockets attached to a string line for his students in Gosford, Australia. <br /><br />The rockets are the little bulb canisters used in whipped cream dispensers and are guided along the string line. <br /><br />The wooden arm slams into the canisters which causes the end to rupture open and the gas is released causing the canister to rocket forward. <br /><br />There is a compilation of both real time and slow motion recording.
