 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the floating paper clip. As always, adult supervision is required. What you need for this experiment is a bowl of water, scissors, paper towels, and a paper clip. So basically you're going to have your bowl of water and paper clip and you're going to cut the paper towels a size a little bit bigger than the paper clip itself. Now this is a small paper clip. You put the paper towel on and then gently lay the paper clip on top of the paper. If you drop it too hard the paper clip will sink. So how does this happen? Well the science behind this amazing experiment works on surface tension. Surface tension is a thin sheet or skin formed by the water. Surface tension tightly holds those water molecules together. Thrust, if the surface tension is and the water remains undisturbed, it'll be able to support the paper clip like this experiment. The paper clip is not actually floating. It is simply being held up by the water or surface due to the surface tension. Several insects such as the grasshopper and the water spider use this sheet to walk across the water. So last one was a standard paper clip. This time I'm using an extra large paper clip and you can see if I put it on very gently, there it goes. You can see the paper starts to sink because it gives it just the paper clip just enough time to get that surface tension and then it's going to be able to stay up if it's not disturbed. Now if you were to take your finger and tap the water it might sink or if you put a little bit of soap on your finger and touch the water the soap would break down the surface tension and it would sink all the way to the bottom.
