So when I was a kid, I loved magnets. Don't we all? And as an adult, I do as well, and I play with it every day. So a number of years ago, I started a company called ADS. We started looking to use computational chemistry to design these tiny, tiny magnets. Nano magnets. Now, what's nano? Nano is really, really small. It's a billionth of a meter. To give you a perspective, if you took one nanometer particle, right, and you put it next to a biological cell, that would be like taking a fist and putting it next to the Empire State Building. So it's really small. And we could modify the surfaces so that it could bind to anything. And we started working with blood and diagnosing illnesses and glucose. And we thought, you know what? It's an aha moment. And this is what Ted's all about. And we say, well, maybe this can work for something else. And we thought water treatment. Well, it's cheap to make. We could change anything on the surfaces to bind to various contaminants. And we could pull it out using a magnet. So I'd like to show you what we've done. So I have E. coli here. I'm going to use a glove. And what I'm doing is I'm putting in about a hundred times more E. coli than is considered safe. So if I were to drink this now, we can all say that I will probably be on the toilet for a very, very long time. Now, right here. I'll put this on the side. Right here. I've got magnetic nanomaterials. Now they're really small. If you could see, they're tiny, tiny, and they're billions of them. And we've used this computational chemistry to make them bind selectively to E. coli and kill it. Well, the magnetic materials are doing are actually, they have these little swords on the surfaces. And they're finding the E. coli and they're poking holes and killing it. Now, I could drink this right now. But would you? And I'm going to pour this out. And right here is a simple magnet. And it's going to pull all of these nanomaterials out. So we've actually, we've killed all the E. coli. And all this is doing is pulling out those nanomaterials so they could be reused and recycled. But this is very cheap to make. And for a few dollars, just a few dollars, people can have safe, pure water all over the world. It's kind of cool. So, it's a life. Thank you.
