After watching this video:
I was intimidated by the idea of trying to make birds and pigs all day and keep the booth moving so I decided to make it a carnival game. I made several birds and pigs ahead of time using the method in the video.
Then I had my husband help me make two slingshots out of wire hangers, rubber bands and fabric from an old pair of pajama pants. We got the idea from the book Mini Weapons of Mass Destruction: Build Implements of Spitball Warfare. I thought about using the rubber bands the way they did in the video however as this was an all day event I felt like if I encouraged kids to launch things with rubber bands the entire staff would be paying for it all day. I also thought the slingshots were a little more authentic and they made it tougher too. It was surprising how quickly some people got the hang of the sling shot and how others were just never able get the hang of it. All in all people seemed to enjoy seeing one of their favorite games come to life.
I did a second convention at another carnival a few months later and all of the supplies held up although two seemed to be the limit as the birds and pigs started looking a little bit bedraggled and one of my sling shots began needing repairs every few Teens.
I plan on doing this again sometime in the near future as a program where each kid will make their own bird and piggy and possibly slingshot....depending on how I think the parents will handle that. It was definitely a lot of fun and I can't wait to do it again.
