Well, he. Swimmer blows some bubble-rings, while another swimmer drops a bottle cap into it, and the cap swirls around the toroid due to the turbulence.

Because I Can
Butane from a lighting wand, dipped into bubble solution, making butane bubbles. When I drop a match in, they burn. In wonderful slo-mo. Note: dipping a lighting wand into soapy water tends to impede the flint’s ability to light the butane.
Quantum Superposition, All Over This Land
Physics and Cake: The ‘observer with a hammer’ effect
[T]his robotic arm is so ridiculously precise that it can measure the diameter of eggs more accurately than any pair or vernier calipers, any laser-interferometer array or any other cool way of measuring eggs that has ever existed. The National Standards laboratories are intrigued.
However, there is a slight problem. Every time the robot tries to measure an egg, it breaks the darn thing. There is no way to get around this. The scientific breakthrough relating to the accuracy of the new machine comes from the fact that the robot squeezes the egg slightly. Try and change the way that the measurement is performed, and you just can’t get good results anymore. It seems that we just cannot avoid breaking the eggs. The interaction of the robot with the egg is ruining our experiment.

Homer in Space
Homer launches into space showing the affects of large acceleration on facial features. Once in orbit Homer adapts quickly to apparent weightlessness as he cleans up errant potato chips. I prefer to call apparent weightlessness “normalforcelessness”. Look it up.

Commentary from Gizmodo
What you’re watching is a piece by artist Chris Burden called Metropolis II, in which every hour 100,000 cars pass through the city of wood block, tiles, Legos and Lincoln Logs. It’s a follow up to Burden’s Metropolis I, which was built on a similar concept but employed only 80 cars. Metropolis II is currently being constructed at the Los Angeles County Museum of Art.
Gaining an Edge(rton)
I recall seeing some stories recently, trumpeting investigations into how cats drink. Some of the data they could have used has been out there for 70 years.
The Physics of Pie Crust
Pie crust phase equilibria: update
As anyone with baking experience knows, the stability region for pie crust is a relatively small area on the wet side of the two phase flour + dough field. This field is generally approached by adding water to a flour/butter mixture
