A video demonstrates how to make hobby rocket “sugar motors” using sugar, kitty litter, and repurposed household items. According to Grant Thompson from "The King of Random" Youtube channel, the rocket costs $0.50 to make and shoots nearly 700 meters (2,300 feet) into the air.

“Sugar rockets are the slowest burning of all rocket fuels, and it's highly unlikely that PVC will explode when using kitty litter plugs and sugar for the propellent,” says Thompson. “Saying that, I wouldn't use PVC with black powder rockets. That is a different story altogether.

Remember, creating unstable rocket motors could result in serious injury and property damage if proper precautions are not taken. As always, check with your local laws, be very careful, and have fun!
