One Methods:Alternate Method
With this wikiHow to you can learn how to make a catapult. You may think that the catapult is just a weapon used in the middle ages, but you can actually have a lot of fun using a mini catapult (most of the fun but with no dragging!).
1Make a complete pass through each of the three silicone bands. Each rubber band should stay in one piece.Ad
2Staple one rubber band to another. Put two rubber bands in the stapler side-by-side, not on top of each other.
3Staple the rubber band string to the tops of the handle.
4Attach the handle securely onto a small wheeled platform. You can construct this platform or use anything small with wheels, like a child's pull toy made from wood.
5Use books, anything else to make a building like construction in the shape of a cube.
6Take a mass of something you want to throw.
7Hold the projectile to the rubber bands.
8Pull the rubber bands back.
9Now let's try and make it hit the target 2 feet (0.6 m) away!
1Start with half of an index card. Roll into a tube about 2 inches (5.1 cm) long.
2Take a hole puncher and make a hole in both sides.
3Make a tube by rolling a full index card so that the tube is about 4 inches (10.2 cm) long, but it MUST fit in the hole in the other tube. Make a small slit in one end about 1 inch (2.5 cm) from the end for the rubber band.
4Use the large paperclip to make what looks like a football goal post with small 9's on each side, these can be made with long nose pliers.
5Insert the large tube into the hole in the small one and then the small one into the 9's and tape in place.
6Place and tape the rubber band into the slit. Hook on and tape to the U part of the handle.
7Take the last card and use it to reinforce the large tube, then take the small cup and tape it onto the empty end of the tube so that the end of the tube is flattened, or use a small paperclip and do the same.Ad
We could really use your help!
- Use a rubber band that's hard because they stretch as far as it should.
- Don't aim your catapult at people, pets, or anything you do not want to break or hurt. Failure to do so can cause damage to property or injuries.
Things You'll Need
- A flat surface out side
- Blocks, books or anything similar
- 3 thick (wide) rubber bands
