James Vyse, a Welsh engineer, has invented the world's first self-cooling can, designed to keep beverages chilled during outdoor activities without the need for electricity. The invention, which operates at the push of a button, uses water and salt crystals to create an endothermic reaction that cools the drink. As beverage giants show interest, the can is set to be trialed in London. Vyse aims to change how drinks are consumed outdoors, addressing the issue of warm beverages and modern packaging's stagnation.
My invention lets the consumer decide when to cool the can down, when at the beach, festivals, picnics. It's alarming to me how many cans are being consumed warm.
At the touch of a button, the walls of the fully recyclable can are chilled - with no electricity, batteries or charging ports involved.
Consumers are picking up cans and travelling with them a lot more. But what happens to the liquid - it cools down.
Although it looks like a 500ml can, it actually holds 350ml of drinkable liquid due to a enclosed, narrow cavity going around its walls.
