(PL) Scientific project - Raising balloons

Raising balloons

If you want to organize a party this experiment can be very useful. It helps you to blow the balloons, but mind the proportions if you add too much baking soda you can create a bursting balloon .
1.       Prepare empty bottles, balloons, baking soda and some vinegar.

2.       Pour some soda to balloons ( we used two, three teaspoons per balloon).

3.       Pour some vinegar into the bottles we poured about 150 ml per a bottle of 250 ml.

4.       Place the balloons on the necks of the bottles.

5.       Straighten the balloons in such a way that the soda goes downs and meets the liquid.

6.       Observe the raising balloons.
