THIS IS SOOO FUN!!! It requires very little effort, and it is bringing great joy and entertainment to both of my kids! You HAVE to do it!
You can follow the instructions on the original link. We simplified ours just a bit, by just tying the string to a piece of bamboo, rather than drilling a hole, and we didn't use a template. Just winged it! ;) We also didn't use googly eyes, because I didn't have any. We spent exactly $0.00 on this project and just used things that were laying around.
Enjoy the pics!
