We can make a double ejector using only the most common materials! A disposable plastic spoon, some popsicle sticks, and a few rubber bands can be done in minutes.
Simple, fun and safe, crumple the paper into a ball and launch it through this catapult. You don’t have to worry about your children getting hurt, and you can also let them experience the working principles of ancient cold weapons!~
You need to prepare:
11 popsicle sticks, 2 disposable plastic spoons, 4 rubber bands, a hot glue gun, and some scrap paper.
1. Stack 2 popsicle sticks and glue them together to form the base of the catapult.
2. Glue 4 popsicle sticks in pairs. ThenThe two sets of popsicle sticks are placed vertically at 1/4 of the sides of the base.
3. Align and glue the 5 popsicle sticks, and place them directly on the base, as shown in the picture.
4. Hold the popsicle stick from the middle to prevent shifting and wrap three layers of rubber bands on each side of the base. Make sure the two vertical rods are still perpendicular to the base.
5. Now take out two plastic spoons and tie the tip of each spoons handle with a rubber band and a popsicle stick. The rubber band should be about 1/2 inch from the end of the spoon.
6. Tear the waste paper into pieces, roll it into a ball and put it on a spoon. Use one finger to press the rubber band holding the spoon, press the spoon with the other hand and quickly release it, the projectile will be launched~
