During the Christmas period, the Meat Fruit is decorated to appear like a plum rather than a mandarin to accord with the holiday season. The ice cream trolley holds a contraption created by Blumenthal and his team, and constructed from Corian by Mike Smith Studio at a cost of £25,000. Powered by a hand crank, it mixes custard and liquid nitrogen to create instant ice cream at the
Liquid-to-gas ratio for gas absorption this ratio gives an indication of the difficulty of removing a pollutant. Most wet scrubbers used for particulate control operate with liquid-to-gas ratios in the range of 4 to 20 gallons per 1,000 actual cubic foot (0.5 to 3 litres per actual cubic metre). Depending on scrubber design, a minimum volume of liquid is required to "wet" the scrubber internals and create sufficient collection targets. After a certain optimum point, adding excess liquid to a particulate wet scrubber does not increase efficiency and in fact, could be counter-productive by causing excessive pressure loss.
