Coketooth Tuesday update

Well the tooth had a break from the coke at the weekend (I forgot to put it back in the coke after taking the Friday pictures!)

Here is the Tuesday picture...still in one piece and it even has some white enamel showing.

 

The picture below shows some mould which started to grow on the surface of the coke.

I wonder why that happened?

I cleaned it off with a tissue and the tooth sits at the bottom of the glass beaker.

Tomorrow is the last day of school so who knows what will be there when we get back on Tuesday 5th January.

Teeth and Coke

The tooth from home.

What we did
We decided to put a tooth in coke because we wanted to see  what would happen. (Laure)

Prediction

I think it will go a bit stained and get holes in it and it will  dissolve. (Toby)

It will start to go black and rot then dissolve. (Ali)

I think it will disappear. (Jessie)

I think it will go rotten and black and then it will start to dissolve and then it will start to go to liquid. (Poon)

I think that if it stays in long enough then it will get holes in it and it will turn into a bit of acid. (Guilli)

What we found out...

At 2:30 - after about 6 hours, the tooth is starting to look a little bit brown...I'm glad it is not still a working tooth in anyone's mouth!

We have a holiday tomorrow - Constitution Day - Falling on December 10 every year, Constitution Day, a public holiday, commemorates the historic event on December 10, 1932, when King Prajadhipok (Rama VII), graciously presented the first-ever constitution to the Thai people. (From Ministry of Culture, Thailand website).

This means that we will be unable to show pictures of the tooth during the next 36 hours...

What will it look like when we come back to school on Friday?

Plants....
