BLACK AND WHITE PHOTOGRAPHY AND ART. dualism of tone

Hello everyone!
Today I want to participate in the BLACK AND WHITE PHOTOGRAPHY AND ART contest, hosted by @axeman

For this contest, I chose a photo from a schedule lesson where my children and I drew a glass of water.
There was a very interesting black background, and we played with optical effects.

The children were very impressed with the fact that when refracted through water, the color changes places, and where the background was white, a part of the black background becomes visible.

Invite your children to conduct such an experiment, it is very fun and curious!
