There is an explanatory website here. I looked at the empty bowl
The website says it is 24cm in diameter. I've estimated the volume to be around 950ml. A normal stomach-full is reckoned to be about 1litre. The review in the Guardian was not very complimentary - read it here
Personally, I don't see the point of spending the best part of twenty quid on a plastic dish with its own sphincter.
Our day-to-day crockery is IKEA Dinera. The cereal bowl holds 450ml, and the shallow large bowl holds twice that.
We frequently have our meals in these bowls, and I am happy with them and their capacity is usually appropriate for our needs. I do not need to be reminded of my innards quite so graphically. Furthermore, that large flat rim of the Full Stop Bowl is just crying out for a triangle or two of bread and butter, or fingers of toast, or a small banana, or pot of fromage frais... Which rather defeats the object of the exercise.
The bizarre shape would not accommodate certain foods very easily. A Cornish pasty, large pork chop, slice of pizza...
I am choosing the Full Stop Bowl as my January Pointless Gadget of the Month.
What would you choose?
