What happens when you use a dinner knife to swipe at the bottom of a coin tower? Do all the coins topple, or could you safely remove each coin one after the other? Check out this cool experiment to see how taking away friction allows you to keep the coins stacked as you swipe. Test your skills and see how many coins you could remove without the tower falling over!
