On The Moon, Maybe
And they wonder why our kids are lagging in science. Fast food carry-out bags are to blame. Sure, the moon's gravity (at the surface) is about one sixth that of Earth, but that's not synonymous with being able to jump six times higher in space. There's more to space than just the surface of the moon; most places in space, you'd be in freefall and unable to jump at all (and 'higher' would be a meaningless concept). Not to mention that you'd have to wear all kinds of protective gear on the moon that would encumber your jumping ability significantly.
Okay, time for me to get back to work.
