N20 [Nothing Too Obvious]

N2O [Nothing Too Obvious] is a psychogeographic research conducted in Hulme a district of Manchester. Nitrous Oxyte cartridges are used for recreational purposes. The gas is made to flow inside balloons and then aspirated. The so-called laughing gas used to whip cream is legally sold. This practice is often carried out on the street, so it is easy to find used cartridges and abandoned balloons at the kerbside. Over a period of ten days, I walked around the area and counted 5,665 cartridges and 167 balloons of various colours, about 50 per cent of which were red.
