Hydrogen+Peroxide+H2O2

How to make hydrogen peroxide: I don't know in your country; here in italy you can buy sodium perborate NaBO3 or percarbonate Na2C2O6 in supermarkets; you mix it with water...voilà H2O2 (diluted).

2Na2CO3.3H2O2 → 2Na2CO3 + 3H2O2

You can also make it from BaO2 and HCl, or by electrolysis of H2SO4

As rocket propellant H2O2 should be highly concentrated however (more than 70% according to wikipedia) and in that case it's very dangerous. Don't know how to concentrate it so much. Read more: http://www.physicsforums.com
