The largest outdoor free floating soap bubble has a volume of 23.3 m³ (822.83 ft³) and was achieved by Sam Heath aka Samsam Bubbleman (UK) at Downhills Park, London, on 11 March 2015.

The bubble solution is made up of water and detergent, and a small number of secret ingredients to reduce the surface tension of the bubble. The bubble was made using 4 metre long fishing whip poles and 11 metres of cotton string, formed into a loop.
