In 1941, the bombings of London created a scary environment for families and children. All citizens of the UK were issued a gas mask during the War. There was a pervasive fear that the Axis powers would launch a gas attack on Britain. The masks themselves were oppressively uncomfortable. Thankfully the feared gas attack never occurred. Children were made to participate in gas attack drills at school. The air of gravity was punctured when the kids discovered they could make fart noises by exhaling sharply through the mask.
