Cool the air inside the bottle by pouring a bottle of cold water. Cooling reduces the pressure inside the bottle. Followed by suction to the balloon inside.01:39720p 201 01:39Balloon placed in the bottle - sucked into the bottle balloon 720p

Nstępnie nakryliśmy glass candle so that the water shut off the air supply to the candles. Then, we have observed that the candle goes out, and the water level increases significantly in the glass. This experiment showed us that the candle does not need air to burn, but only oxygen. If the oxygen content decreases during combustion, then the candle goes out. And when the oxygen is "used up" his place is taken by water, as nature hates a vacuum.02:30480p 137 02:30Candle and Water - Cool science experiment 480p

When throw a lot of salt to water and dissolve it in water - the egg will float on water. When the water and salt solution will have the appropriate concentration, will float an egg in half a glass. The reason for this behavior is the density of the liquid in which the egg is submerged.02:48720p 148 02:48Eggs & Salt Water - float an egg in the middle of salt water - HD 720p

The second part of the experiment Placed two glasses. Funnel at the rate of dye which is at the top of the glass. At the junction of two glasses of dye leaking inside, fills a glass top because the dye is lighter than water.03:14720p 608 03:14Fun for kids with two glasses - cool magical home experiment in HD 720p

The invisible bottle. We need: -glycerol, -glass, -empty bottle. The experiment: First We poured a glass of glycerine so it fills 1/3 of its volume. Second Bottle filled with glycerine we put into a glass filled with glycerol. Results: When we put a bottle of glycerine in a glass bottle was submerged part invisible. This happened because the refractive indices are close to each other.01:441080p 475 01:44How to Make an invisible bottle - Disapparing glass in glycerin 1080p

To perform the experiment you need a needle, straw, water bowl, a magnet (neodymium may be). Rub the same page on the magnet needle, always in the same direction. Then the straw make two floats. Put the needle floats on the water, notice that the needle begins to turn. I stop always pointing the same direction. Explanation The compass is an instrument used for situational awareness. The Earth's magnetic field affects the magnetic needle compass, so that it always shows the direction of magnetic north pole.02:08720p 334 02:08How to make a simple compass?

Injecting Hydrogen Peroxide 30% into tick full of blood The reaction of hydrogen peroxide 30% and blood Реакция перекиси водорода 30% и крови. The oxygen released in the first reaction step is called the oxygen radical. And it is this that has bactericidal activity. The addition of a catalyst for hydrogen peroxide decomposition results in the rapid release and in a short time a large amount of oxygen radicals, destroying all bacteria. Catalyst are substances in the blood. In this case, these substances cause very rapid decomposition of hydrogen peroxide with release of oxygen, which has bactericidal activity.01:311080p 614 01:31Injecting Hydrogen Peroxide 30% into tick full of blood | Hydrogen Peroxide killing ticks 1080p

Explanation: The body of a white reflects the total incident radiation, so it absorbs thermal radiation. Black absorbs card which absorbs almost all of the infrared or heat radiation and a bottle labeled with a card that heats up faster. The air in it expands and pushes a drop of water into the bottle taped with white.02:331080p 1098 02:33Physical experience - absorption of radiation energy 1080p

The light propagates in a homogeneous medium in a straight line at a constant speed. In vacuum, this speed is 299 792 458 m / s and is marked with the letter C. The material in the centers of the light travels at a slower speed, for example, water has a value of 224 799 383 m / s Falling on the boundary of two media material, light can be absorbed, scattered, reflected and refracted. Which of these events occurs, depending on the type of material encountered by the light beam. Frequently we are dealing with partial absorption and scattering of light. If, however encounters the surface is polished metal surface, then there is an almost perfect reflection of the phenomenon.01:281080p 471 01:28Refraction Of Light 1080p
