Gravitational acceleration + optical illusions + how to! In this Get Set… Demonstrate, science teacher Alom Shaha shows step by step how to create Pearls of Water, a physics-defying demonstration that must look even more unbelievable in person than it does on video.
And if you want to see this in person, the instructions, equipment list, and safety notes for setting it up are here (pdf).
