Goodness gracious, great balls of fire!

The first propellant test is done! I was actually rather impressed with the strength of the rocket candy. The force of the burning alone was enough to make the little pellet of fuel in the first test dance around, and it shot the big cylinder of burning rocket candy out of the pipe in the second test.

Anyways, below is the production process:

Start with:

• 65g of Potassium Nitrate (KNO3)


• 35g of Sucrose (table sugar)


• 40ml of hot water (H2O)

Get your hotplate and pot ready:



Mix all of your stuff together, and heat it up. Don't freak out if it starts bubbling, that's good. Just keep the heat down and let the water boil off.



You will begin to get a pasty looking blob, keep heating until there is no sizzling and it starts to get brittle. Like this:



Then, roll it into a little cylinder and have fun!
