Use stacked coins as an immaculate kids’ science demonstration in inertia, friction, and movement.
When it comes to scientific muses, Sir Isaac Newton is definitely near the top of our list. Our favorite laws to break involve physics, movement, and motion! That’s why we came up with the Coin Tower demonstration. Using a butter knife, you’ll remove the bottom coin from an entire tower of coins. What’s the secret? Perform the project to find out!

Stack the coins into an even and straight tower.
Use the dinner knife to swipe a coin out from the bottom of the tower.
See how many coins you can swipe out before the tower topples!
The key to safely removing a coin from the bottom of a stack comes from friction and inertia.
