Kids just love to experiment and learn something new. We offer you to become a magician for a while and do for your baby is a miracle with his own hands. Enthusiastic children's views are guaranteed. And do you will surely get pleasure from what is happening.
In addition, all these experiments, although miracles seem to have a scientific explanation, and thus will be able to stimulate a child's interest in learning.
EGG IN A BOTTLE
We will need: an egg, a glass bottle, a thin strip of paper and a little vegetable oil.
Experience: We need to stick an egg into a bottle with a narrow neck, without damaging either the egg or the bottle. Boil an egg and clear it from the shell. Lubricates the neck of the bottle with oil. We ignite the paper and throw in a bottle and immediately put on the neck of the egg. As soon as the paper goes out, suck the egg into the bottle.
How to explain this? The oxygen is combusted in the bottle, and forms the thin air. In this regard, the pressure is lowered inside and outside normal atmospheric presses and elastically as the egg, it slips through the neck.
HOME rain
We will need: transparent glass container (large suit of the bank or salad bowl), water, shaving foam, pipettes, blue dye (gouache, watercolor, food coloring).
Experience: Pour into water, and the dishes squeezing cloud of shaving foam. In several places the pipette drip dye and wait for when "going to rain."
How to explain this? Painting is denser than water and foam. Therefore, it leaks through the foam and sinks to the bottom.
Toothpaste ELEPHANT
We will need: plastic bottle, a tray, dry yeast, 6% -s hydrogen peroxide, food colorant, liquid soap or a liquid dishwashing detergent and water.
Experience:Put the bottle on a tray, pour into it half a cup of peroxide, a little soap and food coloring. In a separate bowl mix 2 tablespoons of warm water and a teaspoon of dry yeast. Mix thoroughly at least a minute, and then pour the mixture into the bottle. Immediately climb out of it colored foam, similar to toothpaste, which is extruded from a giant tube.
How to explain this? Peroxide decomposes into water and oxygen, and yeast accelerate the reaction, soap bubbles gives. It is noteworthy that the bottle and the foam will be warm as during the reaction gives off heat.
ICE GEMS
We will need: small molds, in which it is possible to freeze the ice tray with walls, salt, paint, pipette.
Experience:Cooking in several containers strong salt solution and adding to them the different paints. A frozen ice in the evening figure laid out on a tray, pipette drips on them brines. Thus, you will paint the ice inside different patterns.
How to explain this? Sodium reacts with ice and heat is released. As a result, the ice melts, it appears small strokes and the paint gets inside. That is why the ice track sprinkled with salt.
dancing Men
We will need:corn starch, water, thin metal pan, a subwoofer or a column, gouache or food dyes.
Experience: Mix 2 cups of starch and 1 cup of water. Pour the mixture on a baking sheet, add a few drops of the dye and set it to the subwoofer. Turn loud rhythmic music, baking presses fingers to the column and watch the dance of colored worms.
How to explain this? Water and starch - the so-called non-Newtonian fluid, it has unusual properties. If it try to influence the power - to beat or compress - it becomes hard. Under the influence of sonic booms of different strength it moves, hardens and changes its shape.
Fountains made of cola and Mentos
We will need: 2-liter bottle of Diet Coke and 5-6 dragees Mentos.
Experience:This experience needs to be done in the open air, or clean up the apartment of a sweet cola is simply unrealistic. The reaction is instantaneous, so all the pills should fall into the drink at the same time. To do this, you can make the groove of the paper on which pills can quickly slip into a bottle or pills to impose on a string and lower it into the bottle. Another point: try to quickly jump aside to avoid the sweet stream.
How to explain this? The rough surface of the pellets helps to quickly release the carbon dioxide from the beverage. He foams dramatically and forcefully pulled out.
VOLUME PAINT
We will need: pancake flour, fine salt, water, food colorings or gouache, cotton swab or brush thick, dense paper for drawing.
Experience: Mix in a jar for 1 tablespoon flour and salt, adding 3 tablespoons of water and paint. So we get the paint of the same color. In the same way we do other colors. Draw brush or cotton swab on heavy paper or cardboard. For each color you want to use a separate brush. Once the masterpiece is complete, place it for a few minutes in the microwave at 600 watts. The paint will harden and drawing becomes volume.
How to explain this? Our paint, like any other pastry rises under the influence of heat.
MATCH -PRIVIDENIE
We will need:a box of matches, a flashlight.
Experience: light a match and keep at a distance of 10-15 cm from the wall. Turn on the flashlight and shine at match. On the wall we see only the shadow of the hand and matches, no fire.
How to explain this?The fire itself being a light source does not cast a shadow.
