507. Ten amazing object lessons using hydrogel beads and a hot pan


What happens if you place hydrogel beads into a hot frying pan?

They start to bounce and make lots of noise! It is called the Leidenfrost effect.

Even if you’ve never heard of the effect, you've probably at least seen it in your kitchen. It occurs when a droplet of liquid, say water, comes in contact with a hot surface, say a frying pan, raised to a certain temperature, and the droplet creates some vapor between it and the pan. As a result, the droplet doesn't actually touch the surface. Instead, it's levitated, skittering around the pan on its vapor cushion rather than evaporating quickly as expected.  (source: insidescience.org)

We offer you ten Biblical object lessons using this cool science experiment.

You can use these hydrogel beads to teach children on a range of different subjects from being filled with the Spirit to the importance of the Ten Commandments, the good and bad kings of Judah and even the conflict between Paul and Barnabas.

Check out these ten object lessons below:

  1. The conflict between Paul and Barnabas
