Sling shot is very cool and easy to do.
All that we need is to find a stick in the right format, and I can say that this is the best part of it. My boy loved walking in the woods to find the sticks. We came home with huge sticks too, just waiting for mommy to have a little time to make a very big sling shot for him.
So I’ve found a colourful tape. Got some elastic and I sew it with a peace of cloth. That’s it! :)
