Cool>Can Self-Cooling Beer
Friday 4th September, 2026
DeltaH Innovations partnered with Brains Brewery to create a beer can that cools a room-temperature drink by up to 15°C when a button activates a salt-and-water reaction. The unusual recyclable packaging gives the technology a tangible, easy-to-understand hook for coverage at London Packaging Week.
Why it worked: It tied a world-first claim to a live demo moment (button-press cooling) at a trade event, with recyclability solving past objections.
The lesson: Consider staging a simple, filmable trigger (press, flip, light) that proves a counterintuitive claim at a timed industry moment.
