"Gee Mum, why are you pointing that thing at me?"

I found Sarah's old watering can (from the days she was a wee nipper) and discovered her brother loves playing with water too. He tried using my big watering can at first, but kept bumping the spout on the ground. Now he has a size which is just right for him!
Give him one bucket of water and one empty bucket, and he pours the water between them. When the water runs out though, he starts turning to the dark side.
