LifeStraw

LifeStraw

By: Anna Burger

Lifestraw turns dirty water into drinking water in under a minute! With this straw all you need to do is take the straw and put the bigger end in the water and then start using it like a straw. While you are sucking through the straw, the water is forced through the filter (doesn’t require chemicals ) trapping bacteria and other contaminates, they are flushed out by back washing. However, there is some carbon on the tip of the straw that neutralizes the taste of the water. This straw is life saving to people who don’t have clean water but can get fresh water with this Lifestraw.

This relates to engineering because engineers had to figure out a way to make a filter system into a small portable straw. They had to do it without using chemicals and making sure the straw would work and last for a long time.
