Most expensive ice cream maker

The G Series ice cream makers, made by NitroCream LLC (USA) are customised and signed by artists. Prices start at $75,000 (£54,484) for these machines, which are designed for restaurants or home kitchens. They use liquid nitrogen to create ice creams almost instantly, by mixing the nitrogen, which turns into gas at -196°C (-321°F), directly with the ice cream mixture.

The G Series were launched in March 2009 but for those with a smaller wallet, a cheaper version, the N2-G4, costs just $34,900 (£23,952)
