Mark Rober (previously at Neatorama) decided it would be cool to add water balloons to a trampoline. It was! He and his nephews jumped along with hundreds of small water balloons, which looks really cool in slow motion. Notice that a body will depress the trampoline surface while the balloons "jump" and stay at the same level.
There’s also a couple of really big water balloons that proved to be super-tough. But even a super-tough balloon can only take so much! A good time was had by all. -via Viral Viral Videos
