Jumping on a trampoline can make you feel like a superhero. Just one little push-off and you’re flying higher than anybody on the ground. There are world records for the longest time jumping, the most one-legged jumps, and even the “Fastest Time to Dress in Formal Attire While Jumping on a Trampoline.” Even dogs are getting into the act: check out this video of a Great Dane (a really huge dog) doing some jumps himself!

*Wee ones:* Jump as high as you can from the floor. Now do 2 more jumps! How many jumps did you do?
