It's fun to make, and a huge hit at birthday parties!
Step 1: Watch the Video!
WARNING: This project uses compressed air as the medium for projecting candy, and thereby poses various safety risks. This project should not be attempted without adult supervision and adequate training. Misuse, or careless use, of tools or projects may result in serious injury or death. Use of this video content is at your own risk.
Step 2: What Is a Candy Cannon?
It uses an electrically activated in-line sprinkler valve, rated at 150 PSI, as the trigger mechanism to release compressed air through the barrel.
Just charge the system up to around 150PSI, and press the detonator button to make it fire!
I built this one for my son's 3rd birthday party to propel a payload of candy to an altitude of around 100 feet, at which point the candy begins to spread out into a giant could of sugary treats, and drop back down, making it rain candy!
You can probably imagine the excitement of the kids with their little treat bags running all around the yard on a candy treasure hunt!
