"This time next year, Rodders..."

Student invents solar-powered light up handbag. Nice plan. I can't believe no-one thought of that before. Like the kid who invented a rainproof rotary dryer... How obvious is that? And while I was looking for that, I found this. Stunning.

One day I'm going to invent something completely obvious which no-one has managed to think of yet and make my millions.
