1. What happened to the food colouring when you added it to the oil? Did this step result in a mechanical mixture or a solution?
2. When you pushed the food colouring through the oil and into the water, did it create a mechanical mixture or a solution? How were the results different from when we mixed food colouring with a beaker of water (without the oil)?
3. What happened to your mixture when you added dish detergent? Why do you think this happened (hint: think of what happens when you wash dishes)?
