Armed with a table and chairs, a white board that says "Ask a Nobel Prize-winning physicist!" and a smile, watch Lederman explain everything from the strong force to the Big Bang.
According to BoingBoing.net, Lederman has done his physics-meets-lemonade-stand routine a few times in both New York and Chicago.
Lederman was awarded the Nobel Prize in 1988 for his research on neutrinos. He currently serves as Director Emeritus of the Fermi National Accelerator Laboratory.
