Dissolving Pumpkins Experiment - Step by Step
Line up five small glass bowls or cups on your work surface. Fill each one with a different liquid - we will test dissolving candy pumpkins in each one!
We used these five liquids: vegetable oil, apple cider vinegar, cold water, milk, and fruit juice. But you can use other liquids that you happen to have in your fridge or pantry too.
Drop one candy pumpkin into each glass bowl. Let the pumpkin soak in the liquid for ten minutes and then check on them. Make some observations about what is happening to the candy pumpkins.
Continue to check on the candy pumpkins every ten minutes for a half hour. How are they changing? Have any of the pumpkins dissolved? Why do you think the different liquids have different results?
Expand the Experiment
Try dissolving other types of food in the solutions, and record the results. Candy corn is another fun choice for Halloween. Or use snacks and fruits you have on hand - like pretzels or blueberries!
Switch up the solutions and observe the results! Try dissolving the candy pumpkins in hot water instead of cold, a baking soda solution, or even mouthwash. What happens?
