Chillsner: The Gadget That Can Cool Your Beer From The Inside (VIDEO)

A new gadget able to chill a bottle of beer from the inside may have just reinvented, or at least refrigerated, summer parties.

The Chillsner is a slim, metal device which is designed to be frozen and then inserted into a bottle of beer.

The user then drinks through the cooling straw, enjoying a beer which is cold all the way through and isn't warmed by your hands.

The device promises "a smooth flow of perfectly chilled beer with every sip. Even the last one" and should be available later this year, for about £20.

Take a look at how it works, above, and let us know if you think you'd pick one up for your barbecue (whenever summer decides to arrive).
