5-Minute Science Magic: Make a Rainbow in a Glass for Kids 🌈

Hey little scientists! 🌟 Want to make real magic happen in just five minutes? Today, we’re creating a rainbow in a glass using sugar, water, and food coloring — an easy, colorful experiment that’ll amaze kids and parents alike!

This is one of our favorite fun science experiments for kids — simple, safe, and full of color and learning. Perfect for classrooms, homeschooling, or weekend fun!

🧪 What You’ll Need

• 4 small cups or jars
• Warm water
• Sugar
• Food coloring (red, yellow, blue)
• A spoon and a clear glass

🌈 How to Make a Rainbow in a Glass

1. Pour equal amounts of warm water into each cup.
2. Add different food colors — red, yellow, and blue.
3. Add 1 spoon of sugar to the red, 2 to the yellow, and 3 to the blue cup.
4. Stir each until the sugar completely dissolves.
5. Now comes the magic! Carefully pour each color into the glass — blue first, then yellow, then red — slowly and gently so the layers don’t mix.

✨ Wow! You’ve just made your own rainbow — no rain required!

🧠 The Science Behind the Magic

Liquids with more sugar are heavier (denser) and sink to the bottom, while those with less sugar float on top. That’s why your colors stay separate and form beautiful rainbow layers! 🌈

🌟 Try This Too!

Try adding green or purple layers by mixing colors — can you make a 5-layer rainbow? Challenge your friends and share your colorful creation!
