Drinks giant Coca-Cola has invented a bottle that chills on the inside when the top is twisted off.
Insiders have hinted that the technology will feature in a new drink called Sprite Super Chilled, which could reach the UK by next year.
The bottles do away with the need to add ice, which dilutes the liquid – but they must be put in a special vending machine to regulate temperature.
Bosses at the US firm hope to cash in on the “super chilled” drinks trend.
Coke and Diet Coke could be packaged in the new bottles if they prove to be successful.
