Blow up the balloon and tie it.
Rub it against your hair on top of your head.
Watch what happens! Your hair will stick up!
Static electricity.When you rub the balloon on your hair, you’re covering it with little negative charges. Now that each of the hairs has the same charge, they want to repel each other. In other words, the hairs try to get as far away from each other as possible. The farthest they can get is by standing up and away from each other.
Coffee, oil, water and salt.
You need water in a glass, then add some oil, then add coffee at the top. Oil is lighter than water, coffee is lighter then oil. Put some salt on the coffee and wait for a while.
Salt is heavier so makes coffee sink. But after a while salt dissolves in water and lets coffee come to the surface.

Copernicus lived at the Castle of Warmian Bishops in Olsztyn, where he would spend the most dramatic days of his life. The castle in Olsztyn was under the jurisdiction of the Kingdom of Poland from the mid-15h century and was administered by Catholic Church officials of the Warmian Chapter. One of them was Nicolaus Copernicus, who in 1516-1521 administered the chapter’s property, including its nearby lands and the castle in Olsztyn.
During his stay at the Olsztyn Castle, Copernicus also conducted astronomical observations. He was particularly interested in planets and issues related to vernal and autumnal equinox. In order to follow the equinox better, he constructed a special astronomical table. Today the table is installed near the entrance to a castle chamber, which Copernicus once occupied and which houses an exhibition dedicated to the astronomer.
Finally we have spring here in Olsztyn-Poland. But the weather is perfect for summer. We invited the weather presenter from our local TV station and she told us about her work. Children could try her hand in presenting the weather for our region.
- Shallow bowl
- Dish soap
- Toothpick or a finger
- Fill the bowl with water.
- Sprinkle pepper evenly across the surface.
- Squeeze a tiny bubble of dish soap onto a clean counter.
- Touch the tip of your finger to the bubble of dish soap.
- What do you think will happen when you touch your soapy toothpick to the water? How will the pepper flakes react?
As the soap moves into the water, and the surface tension changes, the pepper no longer floats on top. But the water molecules still want to keep the surface tension going, so they pull back away from the soap, and carry the pepper along with them.
