Fill one drinking glass about halfway with cold water and the other with warm water. If you have more than two glasses, feel free to try even more temperatures.
Put about 5 drops of food coloring in each glass, trying not to give any of them a head start. You can even use both hands or ask a labmate to help.
Carefully observe how the food coloring spreads throughout the water. Which one is spreading the quickest?
Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
