PRAC

I HAVE FINALLY STARTED MY PRAC. SO HAPPY. well, i have five round takeaway containers. each hold 250mL of liqiud, being sprite, coke, red bull, dare ice coffee(cappachino) and water. Sprite has 10.13g of sugar per 100mL, coke has 10.6g sugar per 100mL, ice coffee has 9.32g sugar per 100mL, red bull has 11g sugar per 100mL and water has no sugar. Teeth and eggshells both contain calcium carbonate and the same proteins. Apparently so do all bones, coral skeletons and shells. http://answers.yahoo.com/question/index?qid=20090107001134AA2RNnG
