01 · CONNECT & PREDICT
Can water walk?
Connect the paper towel bridges. What colour will appear in the middle?
Time is sped up. Real dye colours and paper towels can produce different results.
THE BIG IDEA
What is happening?
Water moves through tiny spaces between paper towel fibres. This movement is called capillary action. The dye travels with the water and the colours can mix.
Simplified model: Time and water levels are sped up and simplified. Real results depend on the paper, water and dyes.
