In Conclusion, our hypothesis was incorrect but correct at the same time. It was incorrect because Ice worked the best out of our three substances, when we assumed that peanut butter would work the best. Ice got the gum out quickly with no mess. Oil and peanut butter were both messy and took time to get the gum out. Both of these substances include some of the same ingredients, however oil worked better. Oil made the hair greasy but, the gum slipped out very easily.
