Bubble-ology

The secret of a good bubble is an invisible bond that connects so-called surface tension, water molecules. Water is a polar molecule, so the plus and minus ends are like magnets that attract each other. Once the water molecules are aligned with each other, they stick together and produce surface tension

You may think that the surface tension of water holds the foam skin together. In fact, the surface tension of water is too strong to create bubbles. You can try foaming with ordinary old water, it will not work! In order to mitigate the surface tension of water, a superior effervescent solution is added to the foam, giving it more elasticity and elasticity. Now it can be more like a balloon skin, stretching out a more beautiful thin bubble, capturing a bubble like a liquid balloon

Do you need to make a good bubble solution at home? The basic ingredients are water and detergent. In this experiment, add glycerin and corn syrup to see if it helps to improve the foam. Which solution is the biggest bubble? Which bubble lasts the longest?

To do such an experiment, you need to be aware of the meaning of the following terms. For more information please help your adults search the internet or take you to a local library!

I read all the information on bubbles on this site from the Exploratorium Museum in San Francisco, developed by Exploratorium scientist Ron Hipschman.

Please read this interesting article and see how the water film and surface tension differ in space.

Bubble science is full of solid science, technology, mathematical content and learning. A wide background section of foam is included. This unit is a natural and exciting extension of the GEMS Guide Bubble Festival that uses desktop activities as learning stations to introduce exploratory lessons in mathematics and science. "The bubble and the children are perfectly combined.These activities are based on science.The students are not only acting but they are learning concepts through experience ... But if the teacher Those wonderful moments will continue as they learn that they created valuable learning. Learn with foam! Try it. "

If the asset price exceeds its eigenvalue, a bubble will be displayed. The word "bubble" sounds awful, but almost all new technologies tend to go through it. There is evidence that railways, radios, and apparently the Internet experienced bubbles before they became mainstream. As Fred Wilson, founder of United Square Ventures told us: "One of my friends has a good route, he said" There is nothing important and unreasonable prosperity " . With this enthusiasm, investors can open wallets and fund the construction of railroads, automobiles, aerospace industries, etc. In this case, most of the invested money has been lost, but most of them It is used. High throughput backbone of the Internet, and many useful software, databases, and server architecture all of which change our lives today ... it is all these speculation zealot "
