Fair testing

Room 15 and I were doing a fair testing science experiment. We got some coke,tea,eggs,hot water and tap water. We cracked the eggs open and put them into cups, then we filled the cups with the liquids. After we put them on the window sill and left them for a week. Since it's been a week we are going to see what liquids have affected the egg shells. It looks like the coke and the tea are affecting the egg shells. In my opinion the coke and coffee are going to be the worst for the egg shells. The tap water isn't looking to bad right now. We all can't wait to unpack the messy experiment that we did last week.
