The Vacuum Flask Test
Like most of us I have collected a number of flasks during the years. Some were gifts some bought and others "inherited"
Last year I bought a couple of Lifeventure flasks, which according to the blurb were all singing and all dancing. Much as I was happy with these I found that when away on trips with Russell (Warthog1981) the performance of his flask seemed to be much better. Until then I had always thought that the performance of steel vacuum flasks would always be much the same. Well time for a test me thinks.
The flasks in the first set of the tests are as follows
From left to right
1) A 1 litre thermos flask that I have had for about 15 years. It is a model not made any more but looks similar to a model they still sell as a mid range flask that sells for about £20
2) A 0.85 litre Vango flask. A budget flask that sells for less than £10
3) A 0.75
