I was in Boots today (a UK pharmacy), and I happened to notice this interesting little product
Magicool Hotweather Cooler
Thinking that sounded like it would be useful when heading to warmer climates, as it:
Instantly cools and refreshes your body and face on hot days and muggy nights.
CFC free, non-toxic and does not discolour fabrics.
I thought I'd look up what the magic ingredients were. I expected a list of incomprehensible numbers or maybe a patented chemical disclaimer, imagine my surprise when I found aqua; yes that's right, the secret (and only) ingredient is non other than water.
All for the bargain price of £4.99
