Simple Science - Experiment Digest # 30

In parallel with the work on the third book, we continue to make experiments and today I present the next digest “Simple Science”.

In this issue:

• We light a match with steam (channel "Science 2.0");
• Artificial snow from diapers (channel "Science 2.0");
• Secret balls (channel "Simple Science");
• Salty ice (channel "Simple Science");
• Cola and milk (from the second book "Simple Science").

We light a match steam

Artificial snow from diapers

Secret balls

These balls are sold in garden stores and are used as soil moisturizers for indoor plants. It is, in fact, the same sodium polyacrylate from diapers (see previous experience). But we wondered how this material would behave if it was immersed not only in water. What we did - look at the video and in the final table of this experience.

Salty ice

The temperature of the ice can be from 0 degrees (Celsius) and below, at 0 degrees the ice begins to melt. When we add salt, we lower the freezing point, and the ice begins to melt. The thread at this moment is immersed in the formed water. But the more water is formed, the lower the salt concentration and the higher the freezing temperature. Gradually, the thread is frozen into a piece of ice.

It is to reduce the freezing point of water that roads are sprinkled with table salt or special reagents in winter.

Cola and milk

This wonderful experience we saw in one of the Chinese videos and decided to include it in our book for children.
