The simple and even for kids safe test from the book "The Experiments for each day" can help to feel the power of air pressure by your hands.

You'll need: the empty bottle, a balloon, a straw.

Insert the balloon into the bottle and try to blow up it. Well as hard as you try to you'll notice it's impossible. Insert a straw into the bottle near the balloon so that the end of the straw would be sticking out of the bottle's neck, and try to blow up the balloon once again. What's happening now? The balloon fills the whole bottle.It happens only when the air inside the bottle is pressed by blowing up the balloon and the air can go out through the straw.

Equipment list: blown-up balloon, an empty can.

Activity instructions: we rubbed the blown-up balloon through our hair. We held the balloon in front of the can and we pulled it towards us. The can started to roll and it followed the balloon.

Conclusion: An electrified from the hair balloon attracts the metal can.

1. Take two sharpened pencils, keep them closer together and poke to any finger. How many pricks of tips did you feel?

2. Poke the arm above the elbow now. How many pricks of tips did you feel?3. Poke the same place above the elbow with the spreaded pencils. How many tips of pencils did you feel now?
Conclusion: there are a lot of sensitive specks for touching in our finger pads, therefore your fingers are feeling both tips of pencils. These specks are less distributed above the elbow, therefore we're feeling both tips only  then, when we spread pencils.

1. Take a small jar and stretch the balloon over the top of the jar. Place  the straw across the top of the jar and stick the straw to the balloon with tape, and put a match under it. Here you  have a barometer - a device that measures air pressure.

2. Place the barometer on the windowsill. Affix the sheet of paper with scale next to the window glass.

3. Watch how the location of the straw changes every day.

Conclusion: When it's fair weather the air more pressures and tightens the balloon's cloth than when it's sleety weather. So, when the weather is getting better the straw will point upwards and when the weather is getting bad the straw will point down.

1. Sprinkle the coarse salt on the table and mix in it a little bit of ground pepper.2. Rub a plastic spoon on a piece of wool cloth.

3. Hold the plastic spoon above the mixture of salt and pepper, and slowly lower it down. What happened?4. Lower the spoon still below. What happens now?
Conclusion: The rubbed plastic spoon in the piece of wool cloth electrifieds. Electrified objects attract other objects. First of all the spoon  attracts the light peppercorns, and lowered down it attracts even heavier salt crystals.

1. We placed a piece of paper towel into the bowl filled with water and we put some of the light metal objects on top of it.

2. The piece of paper towel slowly sinks.
Conclusion: Metals are heavier than the water, therefore the metal objects should drown. However the water surface is like a membrane and it can keep afloat the small light objects.

1. We took an empty bottle and we placed a burning candle behind it.

2. We strongly blew the air into the bottle. The burning candle which was behind the bottle extinguished.

Conclusion: the air flow divides in front of the bottle and it interflows behind the bottle. The candle extinguishes, because an air vortices forms behind the bottle.

Equipment list: a snake cut out from thin napkin, a piece of amber, sheep's wool.
Activity instructions: we took a piece of amber and rubbed it in wool. We put a piece of amber on the snake's head and we raised up it slowly. The snake raised together with a piece of amber.
Conclusion: The rubbed amber in the wool electrifieds and therefore it gravitates the slight snake made of paper.

We analyzed properties of amber: It doesn't melt in hot or cold water, but it drowns. Burned amber emits the smell of resins. It can have yellow, blue, green, black, brown colors and it can be cloudy or clear.
