'This week we have set up a tooth decay scientific enquiry. We want to find out which drink (coca-cola, water, orange juice or milk) causes the most tooth decay. To test this we have put eggs in these liquids and will monitor them each day, looking for any changes. The reason we have used eggs is because the shell of a hard-boiled egg represents the enamel on a human's tooth. So far it actually looks like the orange juice is getting through the shell/enamel the quickest!'
