I loved Frosted Flakes as a youngster, and when I was younger the box of cereal had a floating mail away toy and when I got it, my uncle took 2 of the Sprite 2 liter bottles and filled it with water and put the thing in there and taped it up. He turned it back and forth like an hourglass and it was really cool to watch. My uncle is far away on the other coast, so this one is for you!
