A pyrotechnically modified water rocket.
To make a wooley rocket, you just wrap tin foil around a water rocket and then ultra-
fine steel wool around the tin foil.
Pump up the rocket with water and get it ready to launch. Then light the steel wool with a nine-volt battery and send it on it's way.
The rocket looks like a big
fire-ball arching across the
sky. Have a fire extinguisher ready though when it lands as it will definitely set whatever it lands on
fire!
