Maybe once in the world and wandered centaurs, waving wands, but unfortunately, all that remained in the books of fairy tales. In today's world there is only one thing that can work real magic - chemistry.There is a huge number of chemical reactions that affect their abilities. We offer you to witness some of the most spectacular chemical experiments.
Beads of water
The first thing to do - is sodium acetate. For a little bit, mix baking soda with vinegar, the main thing is not to take a lot. Now put on 10 minutes in the refrigerator. That would not save time, let's do another substance.Calcium bicarbonate, Iodized salt. It took 10 minutes, mix the bicarbonate of calcium with sodium acetate. Add iodized salt in the proportion of 1.2. Now, the resulting mixture should be cooked, about 7 minutes stirring without interruption. After all let cool (about 15 minutes). Now you almost know how to make water balls, there are very few. All is now ready, the water in contact with air becomes a water balloon.
Or just buy the hydrogel in the store

The effect of eating termites fiery metal
Thermite mixture (thermite - chemical, technical) (from the Greek. Therme - heat, heat) - a powdered mixture of aluminum (less magnesium) with oxides of different metals (usually iron).
When ignited, burns vigorously with release of large amounts of heat (combustion temperature is 2300 -2700 ° C). Mixture is ignited by special primer (a mixture of barium peroxide, magnesium and sodium). There are termites welding telegraph and telephone wires, and wires of power lines. In military thermite used as incendiary compositions. In the production of ferroalloys termite with the addition of flux is called the charge

Due to the characteristic sound of the ignition experiment called "the barking dog"

And finally, a couple tricks of physics:
Magnetic particles in a bottle of water
Hydrophobic Nanopolymers
Nanopolymers allowed into production. This substance is able to repel almost any liquid. Hydrophobic coating - one of the first nanotechnology, which entered the market. The substance can be applied to many types of surfaces, including clothes and building materials
Finger, which caused hydrophobic Nanopolymers, with surprising strength repellent liquid
