Try this ex-experiment
Requires:
Glass of water
Glass of coke
2 chicken bones
a toothpick
and 1week of waiting
First take 2 chicken bones and put it in two glasses. Then after 1 week,take the toothpicks and shave the chicken bones.You will find out that the chicken bone in the water doesn't change, but the chicken bone in the coke is easily shaved. Try this after,try bend two bones of those. the bone which is in the water is hard to bend, but the water i the coke is easily bended.S0 donnot drink coke so much!
