What would you do if you had the power of invisibility? Would you sneak around, spy on people, commit crimes, pull practical jokes, or find out what other people really think about you? The military is putting tonnes of money and effort into trying to make things invisible, but don't hold your breath. We introduce a new superhero, Invisibilia, to help us explore some really big questions. How would you behave if you thought no-one could see you? Is it about doing the right thing or is it the "getting caught" part that stops bad behaviour?
