Or it could be some sort of prank. Show people this video, bet them a gillion dollars they wouldn't put their hand in the cylinder for 10 seconds, get a plastic cylinder - cut a hole in it, put the grassy stuff on top, put it on a clothed table that has a hole in the middle, get underneath, wait for victim to put hand in, wait 7 seconds, then reach out and grab victim's hand.
Hard work putting that together, but end result: legendary.
