These real Japanese one Yen coins are made from aluminum and can be made to float on the surface of a cup of water. Use a paper clip to gently lower the coin into the water and it will float on the surface! Adding a drop of liquid dish-washing soap destroys the surface tension and causes the coin to sink. Includes 50 coins and suggested activities. (These coins are nearly impossible to find in the U.S.) 50 coins per package.
