Crumpling newspaper is so easy, your dad can do it with one hand! Or can he? This Father's Day, bet him your allowance that he can't strong-arm the press.
What to Do: Round up five full sheets of newspaper. Have your dad extend his arm and use that hand to crumple each piece of paper into a ball. Give him two minutes to get the job done.
The Scoop on Why He Can't: Odds are, his arm will give out after crumpling just two or three sheets. That's because the muscles he's using don't often see a lot of action, so they tire out surprisingly fast.
