How to Design and Build an Efficient Trebuchet - Middle Grade STEAM Project 

What better way to get in the Halloween STEAM spirit than by building a siege machine? A miniature, candy-throwing one that is. Those ghosts and ghouls won't know what hit 'em!
This trebuchet is just what you need for a middle grade or high school STEAM project. It isn't too advanced and has inexpensive supplies but it is harder than what you are going to get with your everyday Pinterest STEAM activity.
If you need a candy throwing machine for younger ages, check out our Candy Catapult Challenge! A little easier but gets those STEAM brains moving.
