Would you know what to do with a sloither?

Scoil Iosaef Naofa in Cobh, Ireland, has presented partner school, Siglufjördur in Iceland, with two hurleys and a sloither. For those not in the know, that's the equipment used in the Irish sport, hurling.

Jim Wilson, a wildlife consultant who has been working with the two schools, says, "We're looking forward to the first Ireland v Iceland hurling game in a few years' time!"

The BBC World Class team wonders what other surprise presents have been exchanged between twin schools.
