I remember when my brother got a foam-rubber boomerang at the circus one year. We spent hours throwing it at each other in the backyard, desperately trying to get it to come back to us with little success. I figured I just didn't have the knack. As it turns out, it was the boomerang's fault (I knew it!), and I can make one in a few minutes that is guaranteed to work. Sign me up!
There are two different types of boomerang plans available at ManMade. They are both made from cardboard and are simple to construct, requiring nothing more than a marker, a ruler and a pair of scissors. One is made from a cereal box and is lightweight enough to be used indoors. The second is a bit heavier, made from a pizza box, and will fly farther and faster. I decided to give the lightweight fast-catch boomerang a try and managed to make it in about ten minutes.
Following the detailed instructions for 'tuning' and throwing, I had this little gem circling my living room and settling back at my feet by my tenth throw. This project is definitely a great one for kids, especially since you can tie in a lot of information about aerodynamics and the science of flight.
Visit ManMade for the templates and instructions. The project is from David Erik Nelson's book, Snip, Burn, Solder, Shred: Seriously Geeky Stuff to Make with Your Kids
