Perfect Circle Experiment - Can String Really Do This?

Perfect Circle Experiment - Can String Really Do This? 0:29 Making a String form a perfect circle (Surface Tension) For parents and teachers Hey, welcome back to Kids Fun Science! Today, we're going to show you `how to make` a perfect `bubble` circle in this awesome `science experiment`. Discover the fascinating principles of `surface tension` as we guide you through this fun activity. It's a great demonstration of `string manipulation` to create something truly amazing!

This means it maximizes area insight the string without the membrane. Biggest area per given circumferences the string results in perfect circle. The soap water on the outside of the string pulls towards the bubble frame and opens up the string loop. And because the soap pulls with the same strength everywhere, its forms a perfect circle. I used Dawn soap to make my bubble solution. Make sure to dip string into the bubble solution before lightly dropping onto the bubble frame.
