pipe hype

What you need:

• PVC pipe of various length (a pipe cutter helps)
• connectors (elbows, Ts, etc.)
• marbles, balls, or cars (depending on the diameter of pipe you have)

Just let them at it. =) If it is warm out, add water for even more fun!

Add a box for stability (cut out holes for pipes) and make a marble run!

Some curvy pipes.
