For all you ping pong balls out there, get ready to take a tour of San Francisco that will blow your fictional minds. Since 1974 Scott Weaver has been working on his masterpiece, Rolling Through the Bay: an artistic recreation of his hometown that features four rolling tracks for ping pong balls, each taking you down a different path through the city. The Golden Gate Bridge, the Transamerica Pyramid, Haight-Ashbury, Coit Tower, etc. – all the major landmarks of San Francisco are represented. The most amazing part of this ping pong roller coaster isn’t the more than 3000 hours Weaver spent in its creation, nor the intense details shown in the 9 foot by 7 foot by 30 inch model. No, what is truly eye-popping is that Weaver built this moving sculpture entirely out of toothpicks, more than 100,000 in all, collected from nations all over the world. Don’t miss the amazing video demonstration of Rolling Through the Bay below, followed by a short clip where Weaver discusses his construction techniques. A sculpture built from 100,000 toothpicks…and to think that all this time I’ve been using these things to clean my teeth!
