How to make a static electricity motor

Most electrical motors uses electromagnetism in order to transform electricity into mechanical work, but there’s another type of motor, the electrostatic motor, that works differently. Instead of using magnetism, electrostatic motors uses high voltage to attract and repel parts of the motor, causing them to turn. There are many ways of making such motors, but most tend to have very low strength and torque. There are the exception to this rule though, and in these videos from RimstarOrg one such exception is studied in detail. It is called the “Corona motor” and apart from being cheap to build, it also have high enough strength and torque to be a viable motor for practical applications! The downside is that it needs very high voltages, and if you try this build, be extremely careful not to get a shock! And if all possible, avoid using high voltage transformers that plug into the wall socket. They can kill. We are not kidding.

 

 

Decorating cakes with a lazy susan

By using a rotating platform, like a “Lazy Susan”, very interesting decorations can be made. Vincent Lai publicized this inspirational video of how a cake with whipped cream and cake gel can easily become a beautiful work of art. All you need is a lazy susan, spatula and a knife! So the next time you make a cake, learn from this video and make all the guests wonder “How on earth did you make this gorgeous cake?!”
