Claim: Air has higher density than ice and water.
Evidence: Densities of various materials covering a range of values Ice Water (fresh) Water (salt) Air 1.2 916.7 1,000 1,030 
At 1013.25 hPa (abs) and 15°C, air has a density of approximately 1.225 kg/m³ (or 0.00237 slug/ft³), about 1/1000th that of water according to ISA (International Standard Atmosphere).
