Here's a fun little game you can play with your kids and grandkids this weekend. At first, it seems like there's no easy way to accomplish this task, but you'll be shocked when you see the solution!
The puzzle goes like this: Using 10 coins, stack them into a pyramid with one coin on the top, working your way down to four.
Once the pyramid is set up, challenge the kids (or yourself!) to reverse the pyramid by only moving three coins. To get the right answer, you should wind up with a triangle that's now pointing down.
Do you know which coins you need to move?
