Empty cans containing air from Lake Como are being flogged to gullible tourists for £8.40 (€10) a pop.
The sealed 400ml containers are being sold at a bookshop and a restaurant on the lake, as well as in Menaggio and Lenno, two other popular destinations at the holiday hotspot.
They have an aerial image of a motorboat speeding across the idyllic Italian lake and have been on sale since early October.
