Safe for Most KidsReviewed June 2026

This episode is safe and educational for all children, offering a clear, hands-on science lesson about non-Newtonian fluids. The video's strongest positive is its engaging demonstration of how cornstarch mud can behave as both a liquid and a solid, which teaches a key scientific concept in a fun, mess-friendly way. There are no concerns—no ads, no inappropriate content, and no risky challenges—just pure, kid-friendly science exploration.

What Parents Need to Know

This video is a fantastic, low-risk resource for teaching kids about states of matter and non-Newtonian fluids. It does an excellent job of showing a simple, safe experiment using only cornstarch and water, with clear instructions and a memorable visual demonstration. Kids will learn that some substances can act like a solid when force is applied and like a liquid when at rest, which is a great introduction to physics. The only thing to note is that the experiment involves a bit of mess, so parents may want to supervise or set up in an easy-to-clean area.

Talk to Your Kids About

1What are the three main states of matter mentioned in the video, and can you name an example of each from your own home?
2Why does the cornstarch mud turn into a solid ball when you hit it, but become a liquid again when you stop?
3Can you think of other things around you that act like both a solid and a liquid, like ketchup or toothpaste?
4If you tried this experiment, what would you do differently to make it even more fun or to test the mud's properties?

Frequently Asked Questions

What age is this video appropriate for?

This video is appropriate for children aged 3 and up. The content is simple, safe, and educational, with no scary or complex themes, making it ideal for even the youngest viewers who enjoy hands-on play and learning about science.

Is the cornstarch mud experiment safe for young children to try?

Yes, the experiment is very safe, as it only uses cornstarch and water—both common, non-toxic ingredients. However, it can be messy, so adult supervision is recommended to help with cleanup and to ensure kids don't put too much in their mouths or make a big mess.

Does this video contain any hidden ads or sponsored content?

No, this video has no hidden advertising or sponsored content. It is a straightforward educational science video from the Science Max series, focused solely on teaching about states of matter through a fun, hands-on experiment.

What will my child learn from watching this video?

Your child will learn about the three main states of matter (solid, liquid, gas) and discover a special type of substance called a non-Newtonian fluid, which can change from liquid to solid when force is applied. They'll also see a simple, repeatable experiment they can try at home.

Is there any risk of my child trying a dangerous challenge from this video?

No, this video does not feature any dangerous internet challenges. The only activity shown is making and playing with cornstarch mud, which is a safe, classic science experiment with no risky or extreme elements.

How can I use this video to start a conversation about science with my child?

After watching, ask your child to name other things that act like both a solid and a liquid, such as ketchup, toothpaste, or paint. You can also encourage them to try the experiment themselves and talk about what happens when they hit or squeeze the mud.
