Packages from Cyprus

Packages from Cyprus to Czech Republic and to Spain.

Egg into Bottle

You will need: a glass bottle a boiled egg hot water

1. Peel the boiled egg
2. Pour hot water in a bottle for a while
3. Put the egg immediately on the top of the bottle
4. The egg goes through

When you pour warm water into the bottle, the air inside the bottle expands. The egg goes through because the air pressure around pushes the egg inside the bottle.

Hot Air

We need a candle and a pinwheel

We light the candle and we put the pinwheel above the candle. The fire from the candle warms the air. Hot air goes up and moves the blades of the pinwheel.

Air Expansion

Tools: a balloon, two glasses, hot and cold water

At first pour a glass of cold water and a glass of hot water. Put the balloon into the glasses. The balloon in the glass of hot water inflates. The balloon in the glass with cold water deflates. The balloon inflates in hot water because the motion of particles is accelerated due to the heat, and the particles scatter. The balloon deflates in cold water because the motion of particles is slowed down.

Package from Spain

Here you can see some things from Spain we send to our partners in Romania

to ours partners in Poland

and to ours partners in Czech Republic and Cyprus.

Ice cube and pillow

We will need:
a pillow
few ice cubes
2 glasses

I’ll take ice cubes and I put them into the glasses. Now, I’ll give the pillow on the first glass with ice cubes.
We have to wait for 2 minutes.
After 2 minutes we can see how the ice cubes under the pillow melt down as slowly as ice cubes without a pillow. Why? The pillow doesn't heat, pillow keeps a body temperature. So, the pillow can't heat up ice cubes.

A glove that comes to life

To perform our experiment we need a latex glove, a plastic bottle and a water container.

We cut the bottle in 2 parts and then we fit the glove on the top of the bottle.
If we introduce the bottle in the container we can see that the glove is filled with air

The air trapped inside the bottle is pressed and the glove is filled when we introduce the bottle in the recipient.

This increasing of pressure depends on the amount of water that comes into the bottle.

Ice hook

I will try to lift up the ice with a toothpick. You can see it does not work. So I sprinkle salt on the ice. I wait for 5 seconds. Now it works because salt lowers the temperature so the toothpick sticks in the ice.

Making ice cream

First I pour cream on the bottom of a glass and add some vanilla sugar to it. Second I take a tiny cup, and I fill it with snow. Then I measure the temperature of the snow. I pour a lot of salt there, I mix the snowy mixture, and I measure the temperature again. The temperature is falling. When the temperature is around minus 12 degrees Celsius, I put the glass with cream and sugar into it. Third I stir the cream to make it smooth till it´s frozen, and I taste it.
