Shark in the Fish Pond. — The shark is made of stiff letter paper, that is, split up the centre of its body, which centre forms a little round dock with a narrow channel emerging at the tail. The fish should be about two inches long, the hole in the centre being a half-inch in diameter, or less. Put the fish on the water in such a way that the part below the division is well soaked, while the upper part lies on the surface dry. You then dip your finger in a little oil, put one or two drops carefully within the' circle, and the fish will soon be propelled forward. The cause of this is that as the oil lies on the surface of the water it expands, and its only outlet being the channel from the centre of the shark, the force it exerts in getting down the channel will drive the fish forwafcl, until the oil is released and able to spread itself further.
