It is National Chemistry Week
(LINK) and the highpoint of the week will be Mole Day (October 23 ... 10.23 ... you know .... Avogadro's Number ... 6.02 x 10(23) ... man, it kills the mood when you have to explain everything).
So, in the first year chemistry class we tried growing crystals of Potassium Aluminum Sulphate ...
