I scared my little boy half to death in JTF by putting the compost bin over my head and going up to the trolley he was sitting in and shouting 'EXTERMINATE!!' at him. He was bored so wasn't paying attention, and it didn't half make him jump. Luckily he's not a scaredy cat, so it hasn't scarred him for life. He thought it was very funny, so now each time I empty a nappy box or get something in a box from Amazon, he nicks it and tries to dalek me back.
When empty, I can get both kids and me in it, as long as you don't try putting the lid on (I'm claustrophobic). So when turning, I use my garden seat/kneeler thingy to stand on and get a bit of extra leverage. Stinky job, and I'm glad I'm the extra few inches above it, so don't get the aroma undiluted!
