In Pictures: Good clean fun as students hold foam fight

One of the more unusual university rituals has played out at St Andrews in Scotland.

The messy display took place on Raisin Monday, the culmination of a weekend of festivities when St Andrews first years say thank-you to their more senior student “parents” for mentoring them.

The so-called “children” were given embarrassing costumes to wear before they descended on St Salvator’s Quad for a huge shaving foam fight, part of a centuries-old tradition.
