International Women's Day: Norwegian child social experiment brutally illustrates gender inequality

'She was just as good as me, so we should get the same reward'

This International Women's Day viral video proves the point that pay equality really needn't be so complicated.

Norwegian trade union Finansforbundet's campaign shows children being asked to fill two vases with blue and pink balls.

Upon completing the task they are rewarded with sweets – but the boy gets far more than the girl.

Their responses make it clear – pay equality really is child's play.
