I intend to try and give a simple challenge to make people think and also an interesting fact. Sadly I have forgotten this weeks' interesting fact at the moment (thought up in the shower at 7am this morning I may add!) but the challenge still exists. This one is very simple with GCSE science.
Anybody who uses a electric toothbrush or some types of shaver may notice that there are no prongs/contact plates for charging. If this is the case? How does it charge?
I will try to rememeber my fact as it was quite an interesting point!
