Fuck Yeah Fluid Dynamics has an awesome roundup of fluids research that's been recognized with an Ig Nobel Prize. Past winners include a study on why coffee spills when you walk, and another on pressures involved in penguin defecation. Check out the full list at FYFD! » 9/20/13 2:20pm 9/20/13 2:20pm

What the hell is going on with these balls?

Two glass spheres are dropped into a pool of resting water. The sphere on the left causes almost no splash at all, while the one on the right looks like it's doing an impression of your cousin Joey pulling a cannonball at the community pool. The balls are the same size, shape and material. What gives? » 7/10/13 2:49pm 7/10/13 2:49pm

We could watch this bouncing water droplet all. Day. Long.

And now you can, too! FYFD explains the physics behind this mesmerizing clip, which comes by way of Kahp-Yang Suh of Seoul National university in South Korea. » 6/04/13 4:30pm 6/04/13 4:30pm

A simple but elegant demonstration of fluid density

Really loving this demonstration of fluid density from Victoria, Canada's School-Based Weather Station Network. It's incredibly simple, but surprisingly effective. Every grade school on Earth should have this setup. » 4/22/13 9:15am 4/22/13 9:15am

The physics of fire, gasoline, and sheer unbridled idiocy

This is what it looks like when you set a bucket of gasoline on fire, toss it through the air, film it at 2500 fps and then slow down the footage reaaaaal slow. It's totally dangerous, highly inadvisable (don't attempt this at home, etc.) and absolutely awesome to watch. Plus, as Fuck Yeah Fluid Dynamics explains,… » 1/24/13 2:20pm 1/24/13 2:20pm

High speed video reveals the bizarre physics of an ordinary water…

The video is of an effect known in fluid dynamics as the coalescence cascade, which can be observed (provided you have access to a video camera with a sufficiently high frame rate) when a drop of liquid is deposited very gently onto the surface of a layer of the same liquid.
