Timmerflyer is helpful, nice and has lots of friends here

I'm new here and have made some soild rocket fuel. The ones i have made but haven't be able to make enough trust to lift it. For the most part it is easy to make. But still is dangerous so please be careful.

This is the recipe:
100g KNO3, finely powdered
50g cane sugar
30g Karo syrup (corn syrup)

The KNO3 is placed in a pan and heated to 200 degrees in a conventional oven.

This is to keep it from cooling down the sugar syrup too much when it is added.

Warm KNO3 mixes in easier and allows a longer working time.
Sugar and corn syrup are placed in a 1-quart Pyrex measuring pitcher, mixed together, and heated in a microwave oven on "high" until the liquid is perfectly clear.

Heavy shirt, face mask, and gloves are used to make the body more attractive and flame-resistant, just in case.

Sugar syrup is stirred to eliminate any "hot spots." Then the KNO3 added, and everything is stirred vigorously with a wooden spoon. Whilst stirring, mouth of glass container is pointed away from face and other things of importance, just in case.

Here's some links:
