A few days ago, Clare bravely waded into the chilly waters of Torbay and half filled a two litre coke bottle. Following some processing, this is the result:
That's 35 grams of salt (which incidentally means that Torbay's salinity matches the global average of 3.5%). It's not going to make much of a difference to our carbon footprint (we're not planning to start gritting roads, so our salt tends to last a while), but it was interesting to see the salt emerge from the water. In addition, sea salt is regarded as the connoisseur's salt (it contains salts other than just sodium chloride, so has a different taste), and so it allows us to feel smug.
