Escaping Water


What You Need:
  • A glass of water
  • An empty glass
  • Some paper towels
  • Twist a few pieces of paper towel together until they form something that looks like a piece of rope. This will be the 'wick' that will absorb and transfer the water.
  • Place one end of the paper towel wick into the glass filled with water and the other into the empty glass.
The paper towel wick starts getting wet and after a few minutes you will notice that the empty glass starts to fill up with water. This keeps filling up until there is an equal amount of water in each glass. This process is called 'capillary action'. The water uses the tiny gaps in the fibre of the paper towels to move from the cup that is full of water to the one that is empty. This process is also seen in plants where moisture travels from the roots to the rest of the plant.
