Building a kelvin dropper

Описание к видео Building a kelvin dropper

Fun little last minute video. Ended up making this for the kids....

All it takes is some garden wire, a couple of plastic cups, and a couple of metal pots, and maybe some neat little metal door handles. They are actually really quite easy to put together, and are very forgiving! They almost always work!!

Happy xmas, and New Year to you all :-)
