Which liquid will the marshmallow dissolve in first?

In Rousseau today we decided to investigate which liquid a marshmallow would dissolve in first. We used vinegar (to represent the acid in our stomach which breaks down food) milk, water and washing detergent. 14 of us predicted that the acidic vinegar would break down the marshmallow first but 9 thought it would be the washing detergent! Unfortunately, they are all taking a little longer than expected so will have to left over the weekend! Check in on Monday for the result!!
