Anti-Gravity Water Trick

It's easy to keep water in an upside down container with nothing but a card. However, only those possessing extreme skill can keep the water from falling out when the card is removed. Are YOU skilled enough?? Truly an amazing sight - IF you can get it to work!

Still having trouble getting water to stay in an upside-down container? Haven't figured out how to remove the card 'just right?' Here are some hints and tips that will help!

Surface Tension

Surface tension in the kitchen sink. At Berkeley Lab's Molecular Foundry, scientists study surface tension to understand how molecules "self-assemble." The coin trick in the video uses the re-arrangement of water molecules to seemingly create order out of disorder. The same principle can be used to create order in otherwise hard-to-handle nano materials.

Scientists can then transfer these ordered materials onto surfaces by dipping them through the air-water interface, or (as we've recently shown) squeeze them so that they collapse into the water as two-molecule-thick nano sheets.

I found this one on the Physics and Physicists blog.
