Electricity-conducting ink is the coolest thing you'll see today

Remember you were five and Mrs Appleby handed you a "You're a star" sticker for your abstract felt-tip portrait of your mum? Yeah, well, you weren't. You were a dull, unshiny piece of non-star, and your flat, non-electric drawing was too.

But don't worry, soon your art will be worthy of all the stickers in the world, as a Japanese infrastructure company called Kandenko have invented a pen with ink that conducts electricity. 

All you need are a few circuits and bulbs and you can light them up by connecting them with your drawing. Check it out in all its mesmerising glory below.
