Make your own Origami Boomerang
This one is very cool and something your kids will want to learn how to make! To be honest, I was more excited to create this for myself! So how does it work?
As the top wing is spinning forward, the lift force on that wing is greater and results in unbalanced forces that gradually turns the boomerang." As it turns, the lift force on either side of the boomerang creates a consistent torque that makes it loop around back towards where it was thrown from.
