Our Vacation Project
Robert's off work for vacation this week and part of next week, so we found a fun project to work on: a marble run! So far it's got 3 separate tracks, a spirally coil, and an "atom smasher". We hope to also include a loop, a see-saw, musical chimes, and a few other tricks. It measures roughly 2' x 2' x 3' tall.
