Oh, god, why did I think the book Sneaky Uses for Everyday Things would be a good gift for Sherlock?

While it might keep him amused, do you really want to encourage him in home experimentation. I mean do you really need to turn a penny into a radio? It’s a bit like handing McGyver a Swiss Army Knife, a battery and some twisty ties and saying “I bet you can’t make a bomb.”

And yes, this does inspire some fanfic which I will try to get to soon.
