Whistle rockets as the name describes are rockets which emit a very loud whistling sound as it shoots into the air. It contains a pressed pyrotechnic composition called whistle rocket mix. In comparison, the whistle rocket tube is usually about half the length of a similar diameter black powder rocket. No nozzle material is used in the construction of this rocket and it has a very short core making this device an end burner. When the rocket is lit, the composition around the core burns extremely fast, propelling the rocket into the air very quickly. The rocket then changes characteristics, and the material oscillates and the remaining half of the tube acts as a resonating cavity, essentially amplifying the whistle sound. During this process the burning composition still generates enough thrust to continue propelling the whistling rocket through the sky. (Pyroguide.com)
Here is an example of a whistle rocket with a 2" can shell attached to the top. tt stars on top with gold glitter on bottom
Step 1: Materials
-a 3/8 inch bolt (for this size it must be over 2 inches in length)
-loctite epoxy (im using 5 minute quick set)
Step 2: Step 1
Step 3: Step 2
-then insert the cut bolt which is covered in epoxy.
- waight 5 to 10 minutes for the epoxy to start to harden and make sure the bolt is straight.
Step 4: Final Step
for the rammers i use hardwood dowels. you will need to drill a hole a bit bigger then the bolt for one peice. they might break or fray over time but who cares, you can make another one in 5 minutes.
