How-to Make Your Own Catapult From Recycling in 4 Easy Steps.

You can buy your own catapult at your local Walmart for around $10.00 USD but it is more fun to build it yourself. I built mine for free since all the components I used are from recycling materials...

For the slingshot, try to get a V shape branch from a tree like depicted on the picture. You'll also need to large and robust rubber bands and four smaller ones. Finally I use a 1ft vinyl baseboard piece for the sling but you can use what you have such as an old leather strip from a shoe, belt etc.

Cut the two large rubber bands and cut the vinyl base into the shape depicted on the picture.

Take one large rubber band and bind it very tightly to one side of the vinyl sling using one smaller rubber band. Repeat the operation for the other side.

Once the sling is together, attached it using the same technique as the previous step to the slingshot using the two remaining rubber bands. And you're done !
