We use 70 percent hydrogen peroxide (in water) with a kerosene type fuel, sometimes JA-5 (jet fuel) as liquid propellant in our guns. Works good if you ignite it vigorously, otherwise it tends to detonate and blow the gun apart. Burn, don't blow up.

70% Hydrogen Peroxide must be pretty wicked stuff!

It's not too bad, the 80 percent range is where you start getting into some real safe-use issues. There really aren't any hydrogen peroxide manufacturers who will concoct at 80 percent; it's just too dangerous.
