Rainbow Paper Towel Experiment
The Rainbow Paper Towel Experiment is a colorful and engaging science activity that demonstrates capillary action using simple materials, making it perfect for children and adults alike.
Ingredients
Materials for the Experiment
- 1 roll White paper towels Regular paper towels work well.
- various colors Markers (water-based, preferably in various colors) Use vivid colors for better results.
- 1 cup Water Small amount to fill the dish.
- 1 plate Shallow dishes or plates For holding water.
- optional Small cups for color mixing Optional, for mixing colors.
Instructions
Preparation
- Find a flat, clean surface to work on. Gather all materials.
- Using your water-based markers, draw dots or lines of different colors near the center of a paper towel.
- Feel free to overlap colors for a more vibrant effect.
Setup
- Fill your shallow dish or plate with a small amount of water. The water should be enough to cover the bottom without submerging the paper towel.
- Carefully place the paper towel in the dish with the colored side facing up.
Observation
- Watch as the water starts to move towards the colors.
- Notice how the colors begin to spread and mix. Make observations about the colors' movement and blending.
Experimentation
- Try using different colors, varying amounts of water, or testing with different types of paper towels to see how the outcome changes.
Notes
Encourage kids to draw shapes or patterns instead of dots to create unique designs. This experiment can lead to discussions about related science topics such as the water cycle.
