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.
Glycerine or glicerol is oxidized by a very powerfull oxidant, the potassium permanganete. This reaction liberates a lot of heat, it's called exothermic reaction.
Learn about science and you make your own butter. Science has never tasted so good.
"Innovative technology often can make yesterday's science fiction into today's reality. This is particularly true with a prosthetic hand that brings to life fictional accounts of artificial, computer-driven replacement body parts. The bionic hand, called the I-Limb,was named one of the top 50 inventions this year by Time Magazine." From youtube description
