BBC science show Bang Goes the Theory has been criticised for inadequate warnings about the dangers of breathing helium after a demonstration.

The popular BBC1 show featured an item showing how gulping the gas made a presenter's voice squeaky.

A viewer complained that the feature was not accompanied by appropriate warnings.
