The Eggcellent Experiment

In Science we did an experiment on tooth decay. First we got split into 4 groups of 7 and then we wrote our prediction of which liquid would ruin the egg first. Most people put coca cola. We had 3 liquids; orange juice, coca cola and water. Each group had to put the equal amount of liquid in each glass container, then Mr Ward put each container on 4 different window sills in our classroom. A week later we each had a look and all the coke and orange juice was all mouldy but the water was fine. We had a smell of the coke eggs and they had a slight smell of vinegar to them but mainly coke, the orange juice eggs had a really strong vinegar smell to them and the water eggs were fine. Then came the worst part - we had to touch them! Mr Ward put his hand into every single liquid to get the egg out (he even put his hand in the mouldiest of all... the Coke!) When all of the eggs were out we each had to hold them (It was DISGUSTING!) One of the coke eggs (the worst) had mould all over it! We had to fill in a sheet of how it looked, smelled and felt. The orange juice turned out to be worst because most of the outer shell had peeled of, on the coke eggs some of it had peeled of and the water eggs were fine.

So our results of the Eggcellent experiment were... Orange juice is the worst for tooth decay, coke second and water doesn't do anything!
