to make a slingshot you need a y shaped branch. It is good not to make it too thick.
After the branches you need good rubber bands. I used big and stretchy ones.
Double your bands it will help so they don't break. Get some leather or strong pouch. It will hold what you will shoot. i used hardened jeans which is not the best thing to use.
When you've gotten the rubber connected to the pouch connect it to the wood. Its easier to tie with string.
when you have this done you are done. Please like my instructable or follow. also do not follow pics because the slingshot i made is a bit diffrent and might have flaws.
