We'd think this 100,000 toothpick, 34-year labor of love depicting San Francisco and its attractions was pretty awesome on its own, but what really puts our affections over the edge is that this sculpture is also a ball run with four different courses. Have a young marble enthusiast at home? Bring them over to the computer to see this marvel in action!
Titled Rolling Through the Bay, this love letter to San Fran was made by Scott Weaver who estimates it took him about 3,000 hours of work. The four ping pong ball paths take you on different tours of the city and he puts many balls through at once which is especially fun to watch. I highly recommend showing this to your kids.
My son has watched it multiple times and, in Tina Fey parlance, "wants to go to there" and has also asked me how he can jump into the computer to see it better. However, you can avoid answering this question if you're in the San Francisco area - Rolling Through the Bay is on display through June at The Tinkering Studio which is inside the Exploratorium.
You can learn more about Scott Weaver on his website - tell your kids he started building toothpick sculptures when he was 8 years old.
