Here is our preserving experiment. We put two table spoons of Lemon juice, vinegar and salt water over 3 different apples. We left one apple with nothing to see what would happen. We did this over 5 days, starting on a Monday. Each day we did an observation of what was happening to the apples. We found out the the best mix to preserve the apple was salt water.
