While I'm normally a physics guy, I got to give the chemists out there props on this one. Also, props to Bill and Melinda Gates for partnering with me on this video.

Here is a link to learn more about P&G's initiative and to donate (again... not sponsored): csdw.org/

I started a company called CrunchLabs where we build a toy together and then I teach you all the juicy physics for how it works. So if you want to learn to think like an engineer and have really fun time doing it, check out the current promotion where you get 2 FREE boxes at crunchlabs.com

You should also go subscribe to the CrunchLabs YouTube channel cause we’ve got some bangers in the pipeline- youtube.com/crunchlabs

Thanks to these folks for providing some of the music in the video:

Summary: I used some powder that has a flocculant in it to make swampy water drinkable. This can be used in situations where people don't have access to drinking water. Then I met up with Bill Gates and we talked about why we should help poor countries.

I am amazed that almost 40 million young engineers are already helping the brand and the whole world.

It's great to think about the world as a whole when people out there are still thinking about themselves more than even people live just by there house, let alone people with different colors, nations.

I made a very efficient filter using sand, cotton and coffee filters in junior high. You don't need high tech stuff to turn turbid water clean. Though the water should be boiled for 10min before using though. And I mean 10min from the time it start bubbling.
