What do you think will happen to these candies when they are added to different liquids? Time to do some experimenting to find out!

Gather some 4-6 old plastic water bottles or containers. Fill each container with one of these liquids

• Hot Water
• A liquid of your choice

Make some predictions about what will happen to the heart candies when you put them in each liquid. Write your predictions on index cards or small pieces of paper and place them in front of the bottles.
