Any parent wants to be interested in his magical sciences. In order to make physics and chemistry more than just wise names for your baby, I suggest that a small test site be set up at home. Don't be afraid, we're not going to blow anything up. To your attention, the harmless experience with which your child can clearly examine the physical and chemical properties of a substance.

The blacks that mysteriously disappear

We're gonna need:

Normal dining water (possible to take right from the crane), lemon juice, dummy, desktop lamp, white paper sheet.

Experience framework

We take a cup and we squeeze a few drops of lemon juice in it, then we add some water and we'll mix it carefully. After all the manipulations, we'll take a cotton stick and we'll wrap it in the solution. Now, you and I are almost ready to go to the creation of the real miracle. Write a wet stick on paper any word using as a pen. Wait for the inscription to dry and bring the sheet to the desk lamp. By heating him about the filament lamp, you will see the missing message reappearing on paper.

Exploration of magic ink

The whole point is that the lemon juice is an organic matter that, when oxidized (in our case, it triggers heating) acquires brown shades.

Uragan in the bottle.

All we need is a liquid soap, a handful of blonds, a bottle of plastic with a narrow throat and a tightly obsessed roof.

Fill a bottle of water for about three quarters, add a liquid soap in there, and put the plugs in. A lot of lining, turn the body down and spin it intensively. There's a real tornado in front of you.
