Explaining The Spinning Water Demo

In this video I go into the physics of my spinning water demo. I derive the exact curve of the water surface using simple high school...

I've built this classic demonstration that help visualize the effects of the centrifugal force. This is a beautiful example of how we can...

In this video I'm calculating the exact curve the rod fits through in this demonstration, using simple trigonometry. When I first saw...

I made a compact version of this classic science museum demonstration, the rotating rod appears to magically pass through a curved slot....

Shapes of constant width are so fun to play with. The motion initially looks impossible, but once you understand how the simple reuleaux...

I've built a set of shapes of constant width! You can roll on top of them much like circles, but they are definitely not circles, and it...

I made a video explaining some of the things that interested me about this demonstration, some of them where crucial for better...

I've built a pendulum snake (AKA a pendulum wave). I was always intrigued by this type of demonstration and decided to finally figure out...
