How to Float 1 Yen Coins on Water

Trevor English

You are probably familiar with the amazing properties of surface tension in water, but did you know that you can float 1 yen coins and paperclips on top of bowls of water? On first glance, this seems like an impossible task. After all, if you drop a coin into a bowl of water, it just sinks to the bottom and gives no semblance of ever floating. The trick is, you need to lower the coins slowly into the water with some kind of lifting mechanism that doesn't break the surface tension. Check out the short video above to learn a little more.
