Ever wondered how colors travel without touching? This super simple STEM activity with GEMS candy is pure magic for little eyes and curious minds. It’s one of those “wow” moments that needs just a plate, warm water, and some candies.
Perfect for toddlers and preschoolers, this experiment combines science, colors, and joy in less than 5 minutes!
🧪 What You Need
- A plate (preferably white)
- GEMS candies or M&Ms
- Warm water
- Spoon (optional for pouring)
🧠 How to Do It
- Arrange the GEMS in a circle or heart shape on the plate.
- Gently pour warm water into the center until the base is just covered.
- Watch closely! The colors will start spreading from each candy, forming a rainbow swirl.
- No touching! Just observe how the colors meet (or don’t!) in the middle.
💡 What Kids Learn
- Color dispersion
- Water absorption
- Patience + observation
- Predicting outcomes (“What will happen next?”)
🔍 Science Behind It (Simple Version)
The colored coating on the GEMS dissolves in water and spreads out, but since each color has different sugar content, they often don’t mix right away — creating beautiful patterns!
📣 Try This Twist!
- Use cold water instead — does it change the speed?
- Try in a line instead of a circle
- Use saltwater or vinegar and compare results
