Working Mini Cannon

Mini Canon that shoots Mini Marshmallows I had to make a model Revolutionary War cannon for my History class and I thought it would be fun to make it shoot Mini Marshmallows in class. Print Settings Rafts: Doesn't Matter Supports: No Resolution: 0.15 Infill: 20 Notes: The parts easily snap together, and you can load the cannon with a party popper charge. If you cut a party popper open you can pull the string through the hole in the back of the cannon and shoot mini marshmallows or anything else you can fit down the barrel. How I Designed This I designed this in tinkercad and took about an hour to design. I designed it to use a small charge you can get from any small party popper. Project: Mini Cannon Objectives: By the end of this project you will have learned about revolutionary war cannons. ◦Audiences: Anyone from 3-8 grade would benefit from this project. ◦Preparation: You will need parent help \ supervision when taking apart the poppers. ◦Steps! 1. Print out the .stl file in the things tab on a 3d printer. 2. Buy pull string poppers and take them apart carefully. 3. Load the cannon and insert a Mini Marshmallow into the barrel. Pull the string to fire the Mini Marshmallow across the room. Results: By now you should have a working Mini Cannon.
