Tooth picture


Here is the tooth after nearly 48 hours of being in coke.

Have you brushed your teeth today?

  2. Why does the fluffy stuff appear in the Coke? I guess it stays ther for to long and some kind of bacteria is in it.

  3. Samuel,
    I'm sure it is mould which maybe started from some bacteria which was in the beaker or on the tooth. The sugary coke was acting as a food for the mould.
    See the website below for more mouldy facts (in the link, mould is spelt mold as this is the American spelling of the word)
