This is one of my favorite puzzles and it's so simple to build that I decided to share with you all.

If you are a physics teacher you can use this to explain your students how to balance forces.

Step 1: Materials

This is the list of materials that you need to build this puzzle:

  • 1 Rasp (you can buy at your local hardware store)
  • 1 Glue gun (you can buy at your local hardware store)
  • 1 Hammer (you can buy at your local hardware store)
  • 1 Rectangular piece of wood (you can buy at your local hardware store)
  • 1 Nail 5x125mm (you can buy at your local hardware store)
  • 14 Nails 4x90mm (you can buy at your local hardware store)
Nice....It reminded me of this one which I like to use and amuse kids. The center of gravity is not apparent with the forks. The glass edge balance point makes it really interesting.
<p>That's a classic one! I love that to :D</p>
<p>Neat. :)</p>
<p>Thanks</p>
