A Heinz ad teaching viewers how to use tin cans to drum out a song has been banned because viewers could cut themselves trying to copy it.

The ad featured children, teenagers and adults using empty or full Heinz Beanz tins to drum out the rhythm of the song, with the catchline "Learn the #CanSong".

People began to complain that the ad encouraged 'unsafe practice'.

The company said consumers had uploaded their own versions of the song onto social media sites, "which was evidence that copying the ad was not prejudicial to their health or safety".
