The marx generator is a very fun electrical experiment that shows you how to build a high voltage spark similar to lightening. This can be dangerous so do proceed with caution if you try to build one of your own. The project write-up shows you the few parts you need, the process to build it and has videos of a marx generator in action.

This project uses some creative thinking to build a binary clock that runs off of analog circuity. A wheel similar to an encoder wheel is used that slowly spins to give you the time in binary code. A great project for anyone willing to expand their mind beyond the base 10 number system!

The door bell shocking gag is probably as old as door bells, but becareful with this one. The project write-up is lacking on visuals but everything you’d need to know to build one is there. Just be extra careful, I think these guys were really out for revenge on someone.
