The Water Purifying Straw. Not necessarily for use with McDonald’s milkshakes. £8.00.
Using this straw reduces viruses and bacteria by an amazing 96%. It can be used to suck water from a canteen or directly from the source. The column of iodine resin purifies as water draws through the straw. Easy to use.
Wow, 8 euros for 1 straw! Amazing! This must be the most expensive straw on the market!
I think it`s pretty good actually for a water purifier, as long as the iodine doesn`t kill you.
I’m afraid 96% is not good enough, you’ll need 99,99%. Thats the tricky thing with drinkingwater, anything less renders the purification method useless. Lets say you wont be pushing solids for quite a while…
