Liquid asset
HERE鈥橲 a tipple that will moisten your mouth and your eyes at the same time. Michael Zehse spies a company selling water from icebergs calved from .
Svaldbardi describes its product, priced at 拢80 a bottle, as exceptionally pure water that was last in liquid form up to 4000 years ago. Given the remarkable capacity of bacteria to survive millennia frozen in ice, Feedback is tempted to add 鈥渦ntreated鈥� to that description.

The makers of Svalbardi pride themselves on a product that is especially tasteless, a boast that Feedback won鈥檛 contest. For every bottle sold, though, a donation is made to the Svalbard Global Seed Vault, meaning customers can quaff in the knowledge that they are contributing to the cost of running the vault鈥檚 generators, which will be especially needed once all the ice is gone. Those who can鈥檛 afford iceberg water can perhaps wait for the crack progressing through Antarctica鈥檚 Larsen C ice shelf to complete its journey, dispatching an iceberg the size of Trinidad into the Atlantic. Delivery times may vary 鈥� just remember to bring your ice pick.

Objection!
A COURTROOM conundrum: David Head notices a report in The Times of a court case in which the judge 鈥渄escribed the defendant鈥� as a 鈥榮elf-confessed liar鈥�.鈥�
David wonders whether this means the defendant was lying when he confessed to being a liar, and so was not a liar, and so was telling the truth when he said he was a liar, and so鈥�
Dial N for Never
FINDING himself similarly confounded is Dick Duane, who complains that he added his phone number to the UK鈥檚 national 鈥渄o not call鈥� list for warding off marketing agents as soon as it was installed. Therefore he was surprised to receive a recorded sales call.
At the end, the recording told him that if he wished to be removed from the do not call list, he should press 8. 鈥淗ow thoughtful of them!鈥� says Dick.
In a flap
WE FIND ourselves concerned about the optimum number of corners on oatcakes, following a report of a schoolboy injured by flying flapjack (25 February).
鈥淪quare flapjacks have more corners so might be more dangerous,鈥� writes Brian Horton, 鈥渁nd on that basis round flapjacks have an infinite number of corners, so would be infinitely more dangerous. Except that the danger must relate to the sharpness of the corner, so maybe circles are infinitely safer than triangles.鈥�
We feel assaulted by Brian鈥檚 use of the infinite in relative measures, but he does propose a solution: 鈥淪ince Feedback also wants a tessellated baking tray, it is clear that flapjacks must be hexagonal, giving less acute corners that will not cause serious injury when users are hit in the face by one.鈥�
Feedback prefers the following solution: cut flapjacks into circles before serving to children, and send us the leftovers.
Mind your Ts and Qs
ON THE question of what words, printable or otherwise, can be spelled out using chemical symbols (18 February), Keith Perring notes that 鈥渙f the four new elements ratified by the International Union of Pure and Applied Chemistry last November, Tennessine (Ts) seems to help 鈥� but only for forming the plurals of certain slang terms鈥�.
Imperial march
PREVIOUSLY Rex Waygood sought enlightenment about his light bulbs, whose output was measured in very obtuse terms of 鈥�10 kWh/1000h鈥� (21 January). 鈥淐ould they have used a more obtuse power rating?鈥� he cries. 鈥淪urely it would have been much simpler to have used good old British imperial units,鈥� replies Barry Cash, 鈥渁nd defined the power rating as 13 and 2/5th horsepower per 1000 hours?鈥�
But as the UK marches Brexitward, some are keen to reinstate old-fashioned imperial units. Feedback notes that as things stand in the metric system, 1 cubic centimetre of water contains 1 millilitre, weighs 1 gram and takes 1 calorie to warm by 1 degree Celsius. A cubic inch of water, meanwhile, contains 0.58 fluid ounces, weighs 0.58 ounces and takes 0.0036 British Thermal Units of energy to warm by 1 degree Fahrenheit. Best dust off those slide rules.
Chill room
A FROSTY reception awaited Adrian Simper in his hotel room: the air-conditioning dial ran from a chilly +3 K to an impossibly cold -3 K. 鈥淚 asked for an extra blanket,鈥� says Adrian. Maybe those concerned about dwindling ice at the Svalbard Global Seed Vault could open an auxiliary store here?
Marine cuisine
FINALLY, a company with a keen interest in maintaining the terroir of its ingredients (or should that be meroir?). London鈥檚 鈥�Over that all its pizzas are made with 鈥減ure鈥� seawater. Whether it meets the Vienna mean standard (12 March 2016) we鈥檙e not sure, although the restaurant says the ingredient brings 鈥渓ess sodium and more minerals鈥� to make a lighter, more digestible dish.
After all our wrangling over the correct labelling of Himalayan 鈥渟ea salt鈥� (5 November 2016), we never for one moment considered calling it dehydrated seawater.
