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!
