What is it called when you turn a triangle into a three dimensional shape? It’s a tetrahedron! A tetrahedron is a triangle with four faces. Using just a few materials, try and build a tetrahedron that tests the strength of this triangular construction!

What you need:

  • Toothpicks (colored ones are fun)
  • Mini-marshmallows and/or gumdrops

What you do:

  1. Firmly push the tips of three toothpicks into three mini-marshmallows to create a basic triangle.
  2. With two more toothpicks and one mini-marshmallow, attach an adjoining triangle.
  3. Add one more toothpick to finish your tetrahedron.

Add more and more triangles to build a bridge or tower. Then, test its strength by seeing if it can hold up a book or two. You’ll be amazed.
