A small compass.

Building Instructions[]

  1. Create a triangle, keeping the spheres neutral.
  2. Attach three rods to the 3 spheres using the same polarity, and connect them to a single sphere, creating a tetrahedron.
  3. Repeat the previous step at the other side, but use the opposite polarity to connect ot the original triangle.
    • The result is two back to back tetrahedra with rods that are all aligned (except for the ones in the triangle of step 1), creating a nice compass needle.
  4. Use the last rod and sphere to hang the needle from, and observe how it aligns to the earth magnetic field.
