Doodle Science - September 2015



Circulated to schools, organisations and individuals - covering primary science and related bits and bobs.



Violet Ray

This wonderful old bit of Kit is a violet Ray set. It is a fantastic gadget of quack medicine from about 100 years ago. You plug it in and then it turns ordinary electricity into high voltage high frequency juice using a hand held tesla coil. The glass things then fit in the end and are stroked on the effected part of the body. It was said to cure everything but I admit to being too much of a coward to use mine. But it does look pretty as the ray glows in the bulbs and some of the applicators are really quite worrying. .
