Summary

[edit]
Description
Suomi: Vasemmanpuoleisen pallon pohjalla on vettä. Muuten palloissa ja niitä yhdistävässä putkessa on tyhjiö. Kun oikeanpuoleinen, tyhjä pallo upotetaan lumen ja suolan seokseen, vesi vasemmanpuoleisessa pallossa jäätyy muutamassa minuutissa.
English: The ball on the left contains some water. Otherwise the balls and the connecting tube contain a vacuum. When the empty ball on the right is immersed into a mixture of snow and salt, the water in the ball on the left freezes in a few minutes.
