Drop colors into milk and add a special ingredient — watch them dance, swirl, and explode in beautiful patterns! It’s like a fireworks show in a bowl.
What You’ll Need
🥛 Whole milk (skim milk doesn’t work as well)
🍽️ A shallow dish or plate
🎨 Food coloring (4–5 different colors)
🧼 Dish soap
🧹 Cotton swab (Q-tip)
How to Do It
1. Pour milk into the dish — about 1 cm deep.
2. Add 4–5 drops of different food coloring around the center.
3. Dip a cotton swab into dish soap.
4. Touch the soapy end gently to the milk surface near the colors.
5. WHOOSH! The colors burst, swirl, and dance away from the swab!
6. Try touching different spots — watch the patterns continue!
What’s Happening?
Milk is mostly water, but it also contains fats and proteins.
Soap is special — its molecules have one end that loves water and one end that hates it. When soap hits the milk, it grabs onto the fats in the milk, pulling them around like a tiny lasso!
As the fats move, they push the food coloring around with them — creating the beautiful swirls.
The Science Word
This is called surface tension. Soap breaks the milk’s surface tension and the fats start moving rapidly to find new spots to settle.
Try This
🔬 Use skim milk vs whole milk — which has more action? (Whole milk wins because more fat!)
🔬 Try cream (even more fat = even bigger explosions)
🔬 Compare cold milk vs warm milk
It’s chemistry that looks like art! 🌈
