Water Purifying Drinking Straw

100 years before, people just drink the water drom the rive or tap, from the natural resoures. But nowadays the pollution problem is very serious, there are many different kinds of pollution, for example, air pollution, noise pollution problem etc... But we can't stop using air-conditioner, cars. So is not so conivent that if the people who go hiking need water but the one they bought is finished. They just can't drink the river water because maybe the river is full of rubbish or bacteria.

The Vestergaard Frandsen company have invent a new idea, a water purifying drinking straw. Just bring along the little straw and it will help you to purify water, it's really a good idea. Because if you go to hiking, it's not nessessary to bring a litre of water but just drink the water from the rivier with a little straw. It's so convenient, people can drink water anytime in anywhere.

But one thing is that is it really and purify all the bacteria in the water? Will the water be 100% clean and we can well at ease to use it? I think if you want to buy it, you should ask for clear information about it.
