The best thing I've builtWehttamman asks: My dad and I once built a go-kart from chipboard, pram wheels and an engine from a lawn mower. It didn't work... so tell us about your favourite things you've made, and whether they were a triumph or complete failure.

Cat-activated cat squirterAfter suffering with a cat who insists on climbing on every kitchen surface and realising that a squirt of water was the best defense against paw prints everywhere, I decided to build an electronic squirter.
The device consists of an infra-red beam and sensor which, when interrupted by a cat*, activates a pump that takes water from a box and fires it in the direction of the cat*. For added scariness I've also wired in a device that creates a hissing sound when triggered**.
*or forgetful human
**I don't personally find it particularly scary.

NEED ONE.I need either an Instructables-style how-to or for you to make me one.
No, seriously. At least about the first part. Desperate for something to stop our youngest kitten exploring!
