Water Purifying Drinking Straw....

I forgot that I haven't done my business(Kekekeke...I have fixed it already) idea yet...So much hw...Huhuhuhuhu.....Ok...The website in the book doesn't work so I must search in the google...I found one website,And i don't know is it or not!
The website is:http://www.engadget.com/2005/08/18/lifestraw-purifies-water-instantly-for-under-2-a-year/
U can check it.The product is one kind of straw...called LifeStraw...and it purifies water immediately.This product is from Denmark's Vestergaard Frandsen Group whic has the potential to fall into the latter category.The LifeStraw is a water perification kit that draws its power from the person sucking down the water.The LifeStraw uses a combination of mesh filters, iodine-impregnated beads and active carbon to remove particulate matter and bacteria.This product very very useful and it's needed for poor and hot areas all over the world such as Africa,And hot countries like India.And this magic product is very cheap.Just 2$ and we can drink water for a whole year...I think this Invention must be delivered and sent to poor countries and countries near safaries...Because water for them is like Gold for us...It's very rare to see rainy weather...So People there will be happy with this product....(^_^)
