rocket

I set up a string for the rocket to run along and it was about 250 feet long. I made two rockets by mixing potassium nitrate and sugar and they burned very slow with almost no thrust. I made one rocket by baking the ingredients together and it worked very well. After most of the fuel was burned the rocket stopped, sat for a few seconds and shot forward about fifty feet.
