Simple Science - Experiment Digest # 35

Today, apart from our classic experiences, I decided to publish two videos from our permanent viewer. I liked these two videos because of their simplicity and the presence of “wow”.

In today's release:

• the disappearance of glass in the oil;
• cream in liquid nitrogen;
• a lens from a glass of water (from our viewer);
• we cut the infinity (from our viewer).
