This video shows how to play tennis using a soap bubbles and a carpet racket. The soap bubbles are formed by a doubled layer of soap at extremities and a layer of water at center.
The polar part of soap molecules are bonded to the water and the nonpolar part are on the outer side.
Carpet is composed of polyester, as the bubble's outer side, so the interaction between them is very weak and the bubble do not pop out.

Each chemical element has its own Identity given by the color emited when it is burning. The colors in fireworks is due a diferent kind of elements. Copper give the color green, sodium give the yellow one. This video shows a lot of diferent elements and its correspondent colors.
Learn about science and you make your own butter. Science has never tasted so good.
Flame test as you never seen before

The eggshell has calcium carbonate in its composition. Acids as vinegar (acetic acid) reacts with calcium carbonate generating calcium acetate and carbon dioxide. After all calcium carbonate be consumed will remain just the proteins of the eggshell making a elastic shell.

This video shows how to make hot ice, a supper saturated solution of sodium acittate that crystallizes when you disturb it or add a small crystal.
Universal indicator is used to find out the approximated PH of some substance. This video shows at first a ph 14. As some acid is added the color starts to changes. In the end the beakers bottom have a different ph from the top, so the various colors appears.

Mirrors always fascinating the human being, the possibility to look ourselves face to face is a mark in a culture of a people. That’s why these objects were so precious in ancient times and still are for some indigenous tribes.
Nowadays it is used, beside the self admiration, in cameras, telescopes and satellites.
When the man first went to the moon, they left a mirror there, so today using a laser is possible to measure the distance earth moon very accurately.
This videos shows how to make a mirror by using the glucose to reduce a silver complex. The metallic silver is deposited in the flask forming a mirror’s surface.

Learn how to do a sodium dichromate volcano
Sodium dichromate is a orange solid. During its decomposition N2 , water and chrome oxide are liberated. The total volume increase in about 30 times. Some chrome oxide dust and the heat liberated make it really seamed with a true volcano.
