London -- Foam logos from publicity company Flogo were being produced outside the Tate Modern on the South Bank in London this morning.
No polyurethane was involved: they're just a sophisticated soap solution, turned into advertising in the air.
Flogo has developed sophisticated bubble systems and extrusion deviceswith the aim of keeping the customer's logo or symbol visible for aslong as possible, at an appropriate height. A grey February morning in London doesn't do the concept justice. Foam snowflakes or Mickey Mouses look much better against a clear blue sky.
Foam uses such as this appear repeatedly in the news searches Urethanes Technology International carries out every day, most regularly fire-fighting foam, but quite often food foam. This a first -- logo foam while commuting, although I did see a sofa floating down the Thames one morning.
These aerial advertising slogans, developed by North Carolina dentist Brian Glover and partner Francisco Guerra, an Alabama-based special effects expert, are reputed to have no long-lasting health or environmental effects -- although they they have been described as visual pollution by some.
