It is best to use a Tam Maker’s Rube Goldberg Kit, available for $20 (rent) or $50 (buy) when you order your tickets. If you live in the Mill Valley area, we will deliver the kit to you before the first class.

  • 1 spatula that has a hole at the end of the handle OR 1 ruler that has a small hole near the end of the ruler.
