Students at St Andrews braved the grey autumn skies of Scotland to celebrate 'Raisin Monday', a tradition in which first year students take part in a mass foam fight.

The convention in different forms dates back to the early days of the university, which was founded in 1614. New arrivals would give senior students a pound of raisins to thank them for their help in adapting to university life, in exchange for a receipt written in Latin.

Failure to produce the raisins could result in them being doused in a fountain. Nowadays, the gift is a bottle of wine, and the dousing has been replaced by a foam fight.

Students taking part in the festivities this year donated items to a collection for the Storehouse foodbank in St Andrews.  'Raisin Monday' is part of a tradition at the university in which older students 'adopt' first year arrivals as their 'children' to help guide them through the first weeks of university life.
