About our bulk supplies
What are these supplies for?
They're the same parts used in our kits and free project pages, sold in classroom quantities, so you can run a project without buying a kit.
Which part goes with which project?
- Plastic Project Wheels (100): 1/8" hole, fits 1/8" dowels. Used for the mousetrap, rubber band, sail, crash test and slingshot cars.

How much do I need for a class of 30?
We generally recommend buying enough for each project you plan on making plus an extra 10% for backup or for making your own design.
