Alas, here are the results of the tooth experiment: what happens when a tooth is left in a jar of coke? Three kids predicted the tooth would disappear, except for Sela, who said it would remain the same. Predictions were posted next to the jar, which was placed on the kitchen windowsill. Technically, neither were correct. Sebastian was bereft that his prediction was less than prophetic. We never posted original pictures of the tooth, but it was an old, white… okay beige, tooth at the start of the experiment.

In total, the tooth remained in the jar for about 6 – 8 weeks. (We were busy and life happened.) Eventually the day came to remove the tooth. While the tooth never dissolved, it still looked thoroughly disgusting. Parts of the tooth where there was sold oft tissue had been cleaned out quite effectively. My theory: the moistened tissue was dissolved by the sugar. The rest of the tooth was cola brown all the way through. Yes, the cola stained the entire tooth through to the centre. Using a hard knife we attempted  to scrape off the tooth's surface only to find the tooth stained underneath. The attached pictures pretty much tell the whole story. (Sorry that the 2nd one is a bit fuzzy.) At first this turned the boys off colas, but now they've forgotten unless we remind them. The girls never liked soft drinks – they prefer water and/or juice.
