If you throw a boomerang, it turns around and flies back at you! Why? A boomerang is a curved stick with 2 slightly-different shaped sides. The wind passes under one “wing” at a different speed from the other wing, which makes it fly on a tilt that sends it in a big loop that (usually) comes back to you. The farthest-flying boomerang sailed 780 feet from the thrower — more than 1/10 of a mile!

*Wee ones:* Boomerangs are curved, not straight. Find 2 straight lines in your room, and 2 curved lines.

*Little kids:* If your 3rd boomerang throw comes back to you, then your 4th throw, then your 6th, what number throw didn’t come back? *Bonus:* Which flies farther, a 100-foot boomerang throw or a 40-foot throw?

*Big kids:* The longest-flying boomerang flew 2 minutes 59 seconds. If it had stayed in the air 1 second longer, how much time would that have been? *Bonus:* If your boomerang flies 38 feet out, your friend’s throw flies 60 feet, and your next throw flies halfway between those 2 distances, how far did your boomerang fly?

Answers:

*Wee ones:* Straight items might include the edges of doors, windows, or the bed; curved lines might include edges of doorknobs, clocks, or squiggly lines on clothing.

*Little kids:* The 5th throw. *Bonus:* The 100-foot throw.

*Big kids:* 3 minutes, since that’s the same as 2 minutes 60 seconds! *Bonus:* 49 feet.
