Students from St Andrews University indulge in a tradition of covering themselves with foam to honor the 'academic family' at St Andrews in Scotland, Britain, October 17, 2016. Every year the 'raisin weekend' which is held in the university's Lower College Lawn, 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.
