Crayola, a company best known for those different colored snack sticks, has just released an audio ruler for kids. You roll it along and it leaves a trail of disappearing ink to ensure that you measured what you wanted. It will then tell you how long the distance was, in quarter inch increments up to a foot. A foot? That's pretty weak, for $8 I was expecting a little more. I was just about to order one too, to measure my ding-dong. I can hear it now. "Your ding-dong is three feet long and you should tote your balls in a wheelbarrow." No joke I should.
