KIT LIST
Two flexible straws
Scissors
Three glasses
Water
Food colouring
1 GATHER YOUR MATERIALS
Collect all of the materials, making sure that the three glasses are all clear and similar in height.
2 POUR WATER
Line up the glasses and fill the left and middle glasses to the top with water.
3 ADD SOME COLOUR
Add some food colouring to the cups with water. This isn’t essential but will make the experiment better to view. Separate colours will show how water travels through the glasses and changes colour.
