Mentos Cannon

pinshape

I needed an effortless way to unleash Mentos into a two-liter soda bottle. This design holds five Mentos, plenty for a fifteen-foot fountain, and features two one-millimeter holes to accommodate a paper clip that keeps the Mentos from falling out. A screw head securely attaches to the two-liter bottle, with a tapered nozzle on the opposite end. Tie a string around the paper clip and then pull it to release the Mentos into the soda, triggering the reaction. A second or so later, the soda will erupt out through the nozzle. I suggest using two walls and PETG as materials for maximum strength and water tightness. Have fun creating! This design was created using TinkerCAD with precision and care.
