Laughing gas, also known as nitrous oxide, is colourless and has a sweet taste. Usually, our body has laughing hormones which naturally trigger and create a laughing sensation but this nitrous oxide artificially triggers laughing hormones, which makes us laugh continuously for around 5 to 10 minutes.
