Fun With Antibubbles
Up on the International Space Station, astronaut Don Pettit demonstrates the weird behaviour of antibubbles (droplets of liquid surrounded by a thin film of gas – the opposite of ordinary gas bubbles).
Part of his ongoing series of physics experiments in collaboration with Physics Central.
A Physics lesson In Cabra
Louise F writes:
Every time I pass this sign in Tesco, Cabra [Dublin], it annoys me. From my rudimentary knowledge of the laws of physics I think it’s impossible for something to create more energy than it uses as in a fixed system like this store. Energy cannot be created or destroyed it can only be converted from one form to another. Surely this sign is wrong then? But even if I’m wrong about this the sign is very annoying.
Meanwhile, On The International Space Station
Reel NASA sez:
Expedition 30 astronaut Dr Don Pettit uses knitting needles and water droplets to demonstrate physics in space through ‘Science off the Sphere.’ This is part of the first video in a series for a partnership between NASA and the American Physical Society to share unique videos from the International Space Station with students, educators and science fans from around the world.
