I experimented with catching earthworms by charging an electrolytic capacitor with a DC motor.
The earthworms can be used as chicken feed or fishing bait.
This experiment is very dangerous and should not be followed carelessly.

![12V car bulb connect to 220V directly
This is series capacitor current limit circuit. Widely used in transformerless power supply.
However, it is dangerous because of the high potential difference with the ground.
In this kind of circuit, may damage the bulb by over current flows due to harmonics. (Current : 2 × π × f × C × V [A] ) 12V car bulb connect to 220V directly](https://i.ytimg.com/vi/4HI3JEzjyu8/mqdefault.jpg)
