Students from St Andrews University have let the foam fly in a tradition of honouring their "academic family" at end of the annual Raisin Weekend.
The Raisin Monday celebrations fall in the middle part of the university's Martinmas Semester.
They take their name from when raisins were given to the "academic parents" - usually older students - to thank them for welcoming new students to St Andrews.
The gift of raisins has now transformed into a full-on foam party.
The Students’ Association Charities Campaign sells cans of shaving foam at the university's halls of residence.
It is also traditional for academic mothers to give each of their children "Raisin Strings", often decorated with trinkets that mean something to them both.
Students take Raisin Receipts along to the foam fight - traditionally written on parchment - with a special Latin phrase.
There have been reports that students were warned to rein in their celebrations after concerns of some anti-social behaviour last year.
Sunday involves an afternoon party and a dinner, followed by Monday's procession and foam party.
The Raisin Monday foam party event takes place at the university's St Salvator's Quad.
Students are urged to make memories that last, have fun, be safe and look out for each other.
After the foam party comes the clean-up.
