What can it be?



I'll give you a clue; it's NOT a Ping Pong ball (it's smaller), or anything to do with sport.

I'll give you another clue (below).


Answer: It's the 'widget' from inside a can of Draught Guinness.

During the canning process, liquid Nitrogen is added to the beer, which, when the can is closed, vaporises and expands, and fills this small widget through a tiny hole. When the can is opened the pressure drops and this gas escapes, forming the creamy head of a classic draught Guinness. Pure genius.

So, there you are. If you already knew all this, then count yourself a brain-box. If you didn't, you can thank me for littering your head with yet another bit of totally useless information.

  5. No .... didn’t know that ........ I wouldn’t say that I’m a Guinness drinker but, I love that creamy part ....... I wish it was all head as it gets too bitter after that for me !!! I remember my Mum and Dad visiting the Guinness factory in Ireland ... they were gifted some of those Wade China Guinness figures. I’ve got them somewhere. ..... and, do you remember the Guinness clock at Battersea funfair. I sat for ages watching and waiting for it to do its thing on the hour. XXXX

    1. Several of the Seaside Towns had Guinness clocks, they were always a great attraction; Guinness's publicity dep't was one of the best ever.

  6. I did actually know that was a 'widget'! Our grandson had a 'ball race' game in which two/three/four people choose a hole to drop small balls into, and wait to see which one 'wins' the race to the bottom of the tower. Obviously, it's always the same hole, but at eighteen months of age, he didn't twig to that!
    The balls vanished after a few days, ping pong balls were just a tad too big, but widgets are perfect.
    Poor Grandad had to sink a few cans of Guinness Draught to keep the game viable, how sad for him! X

  7. Its a fix for getting the right head on canned Guinness, glass bottles are better....proper pulled draught is infinitely better..but if you can't get either of those...I'd try something local!!

    1. The canned 'draught' Guinness is actually very good. Although I do find the cans too small.

    1. My experience of 'widgets' runs only to Guinness. I'm pleased to hear that other beers also use them (I've not heard of Kilkenny Beer).
