Safe for Most KidsReviewed June 2026

This episode is safe for all kids and teaches a fun, hands-on science lesson about non-Newtonian fluids. Host Phil clearly explains how to make cornstarch mud and demonstrates its strange properties, making it both educational and entertaining.

What Parents Need to Know

This video is a great introduction to states of matter, specifically non-Newtonian fluids. The host, Phil, provides a simple recipe (2 parts cornstarch to 1 part water) and shows how the mixture behaves like a liquid and a solid. There is no questionable content—just pure, engaging science. Parents should be prepared for a possible mess if kids try the experiment at home, but overall it is a safe and valuable learning experience.

Talk to Your Kids About

1What are the three main states of matter, and how did the cornstarch mud behave like each one?
2Why do you think hitting the cornstarch mud makes it solid, but letting it sit turns it back into a liquid?
3Can you think of other things that act like both a solid and a liquid?
