Students from St Andrew's University indulge in a tradition of covering themselves with foam to honor the 'academic family' on November 4, 2013, in St Andrews, Scotland. Every November the 'raisin weekend' which is held in the university's St Salvator's Quadrangle, is celebrated and a gift of raisins (now foam) is traditionally given by first year students to their elders as a thank you for their guidance and in exchange they receive a receipt in Latin.
