Largest ant farm

According to Official Guinness Records,

The largest ant farm habitat is 1.2 m (3 ft 11 in) height x 0.9 m (2 ft 11 in) width and 0.08 m (3 in) depth, achieved by Colgate Palmolive Ltd in Singapore, Singapore, on 28 December 2008.
The habitat was used as a promotion for Colgate Anti Cavity toothpaste. Bus shelter ad was set up by BusAds of Singapore with special gel manufactured in China. About 200-300 ants were released into the habitat, which started digging within 24 hours, creating mini tunnels within the gel, thus giving the impression that the 'tooth' had cavities.
