A self-styled nutty professor dad and his son literally had a blast on Saturday when they adapted a toy rocket launcher to give it some extra fire power.<br /><br />Australian science teacher Jacob Strickling and his son Samuel, aged 9, attached a homemeade "marshmallow cannon" to the spongey toy rocket launcher.<br /><br />Next, they squirted in some fuel and then used a starter cord to produce a spark in the chamber of the cannon. <br /><br />The result was pretty impressive - the rocket flew through the air at high speed, right the way across the garden.<br /><br />"The spark ignites the fuel and the expanding gases produced cause the rocket to be ejected," Strickling explained.<br /><br />Please do not try out this "experiment" without adult supervision.
