Can water walk between glasses? Yes, it can! And it makes a beautiful colorful display. Try this amazing science experiment with help from a grown-up.
What You’ll Need
🥛 6 clear glasses (all the same size)
🎨 Red, yellow, and blue food coloring
🧻 6 paper towels
💧 Water
Step-by-Step
1. Line up the 6 glasses in a row.
2. Fill glasses 1, 3, and 5 with water (skip the others).
3. Add red food coloring to glass 1, yellow to glass 3, and blue to glass 5.
4. Fold each paper towel into a long strip.
5. Place one end of a paper towel in glass 1 and the other end in glass 2. Do the same for the rest — connecting each glass to the next.
6. Now wait. After 15 minutes you’ll see something amazing! 🤩
What Happens?
The colored water slowly “walks” up the paper towels and drips into the empty glasses. Even better — when red and yellow meet, they make ORANGE! Yellow + blue = GREEN! It’s like magic!
Why Does This Happen?
Paper towels are made of tiny fibers with little gaps between them. Water gets pulled into those gaps through a process called capillary action. The same thing happens in plants — water travels up from the roots to the leaves the same way!
