Anders lost a tooth at Pre School last week. This is the second tooth he has lost. We asked him if he could write a letter to the tooth fairy asking him to leave the tooth for a Pre School experiment.
He wasn’ t sure about this. He took the tooth home for a think. The tooth came back this week. The tooth fairy was fine with the idea.
We put the tooth into a plastic cup with some coke. What do you think will happen?
“It will go black.”
“If we wash it in water it will go white again.”
After 24 hours the tooth has gone considerably brown.
We will keep it in the coke over the next four days and see what happens.
Then we will try to wash it clean in water.
