Effects of Pineapple on Jello

The video tutorial explores the effect of different types of pineapple on jello firmness over time. Fresh, frozen, and canned pineapples are added to separate jello containers, with one serving as a control. Observations are made at 5, 10, and 15-minute intervals, noting the firmness of the jello. The enzyme in pineapple that breaks down protein is discussed. The experiment is set to continue overnight for further analysis.
