Cool Science Experiments For School – Exploding Colors & Unbreakable Egg



Here are some more cool science experiments for school or to do at home. Kitchen Chemistry Kal, who is one of The Quirkles, KOLR 10, and Terri Johnson talk about fun science experiments for children that can be done in the kitchen with food. They demonstrate this through some fun and cool experiments involving food coloring, milk, and the unbreakable egg!

Make sure you watch this video too! It is an introduction to all of The Quirkles characters where you will discover why everyone is talking about these wonderful little scientists and their cool, simple, fun, and easy science experiments for children. http://www.youtube.com/watch?v=owlwDHjFCWM

The Quirkles® are 26 imaginary scientists that help children everyday, all over the world, develop a love and appreciation for science. They are an educational based series of books that offer an easy new way to integrate literacy and fun science at school or at home for kids. Each book is full of vocabulary builders, character education lessons, and two related easy science experiments for children that allow for hands on activities, helping to reinforce the topics that were just read. The series was created by teachers, and each story teaches/reinforces the phonetic sounds that serve as the building blocks for reading, while also making science—earth, physical, and life—fun and cool to learn.

Hypothesis: Stated as a question: Does liquid soap break the surface tension of milk?

Objective/Purpose
To demonstrate how soap can break the surface tension of milk while creating a color burst

Procedure:
Pour enough milk in the dinner plate to completely cover the bottom and allow it to settle. Add one drop of each of the four colors of food coloring – red, yellow, blue, and green – to the milk. Keep the drops close together in the center of the plate of milk. Place a drop of liquid dish soap on the tip of the cotton swab. Place the soapy end of the cotton swab back in the middle of the milk and hold it there for ten to fifteen seconds. See what happens. Wow!

Conclusion:
Milk is mostly water but it also contains vitamins, minerals, proteins, and tiny droplets of fat. When you add soap, the weak chemical bonds that hold the proteins in the milk are changed. The molecules of protein and fat move away from each other in all directions. The food color molecules are shoved everywhere, too . At the same time, soap molecules form a cluster called micelles. These micelles distribute the fat in the milk. This mixing fat and soap causes swirling and churning where a micelle meets a fat droplet. When there are micelles and fat droplets everywhere the movement stops. Another reason you see the exploding colors is due to surface tension. Because milk is mostly water it has surface tension. This means the drops of food coloring in the milk tend to stay in place until the liquid soap breaks the cohesive bonds of water molecules. The food coloring will burst into colors moving throughout the entire surface.

  1. As the micelles form, the pigments in the food coloring get pushed around. Eventually equilibrium is reached, but the swirling of the colors continues for quite a while before stopping.

  2. When you introduce detergent to the milk, several things happen. The detergent lowers the surface tension of the liquid so that the food coloring is free to flow throughout the milk. The detergent reacts with the protein in the milk, altering the shape of those molecules and setting them in motion. The reaction between the detergent and the fat forms micelles, which is how detergent helps to lift grease off of dirty dishes.

  3. @EnvyMeJJ Science can be unpredictable sometimes! You should always do experiments in a controlled and safe environment. Hopefully it wasn't too hard to clean up!

  4. @psaini94 we do not make those shirts. They are actually tie dyed lab coats that you can get off of the Steve Spangler Science website. Here is a simple video that we created on "Tie Dye Science" (search: Fun Coloring Activity for Children: Tie Dye Science) – Here's another great video by Steve Spangler that shows you how to tie dye fabrics too (search: Spangler Tie-Dye Experience)

  5. @crisXD1032 Thanks for the question! It does not have to be Joy, but we have found Joy or Dawn work the best in most of the experiments using dish washing liquids. Off brands will work as well. Great variable for inquiry science! Try different kinds and monitor results. However, the creators of the Quirkles prefer Joy or Dawn!
