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...

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

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

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