His brought a camera, a very high speed camera called the Phantom Miro, which can record video extremely fast. Several 1000 frames a second. So you might ask, Why does that matter? And the answer is that many chemical reactions are really, really fast, and so we're really interested. Well, he's not a very good actor. Seems so happy. I can't believe you think. I'm sorry. Go ahead. You may ask, why on earth should we want a high speed camera? And the answer is that chemical reactions are very fast on dhe. We or least I, as a chemist, have not seen these reactions recorded at high speed. And I believe and I think Brady does as well that some of our reactions might look quite different when we video them at a high speed. And we've done quite a lot of videoing, and we're going to do some more as a taster of what we're going to upload over the next few months, I thought you liked. See one or two clips. Justice. See quite how amazing this high speed camera can make chemistry appear even more exciting. The knife hold. I'm very happy to be here. I don't really think I can express how happy I am to you on when you heat it up. Some of the liquid is going to boil, so it'll create pressure. Steve, I was trying not to pee my pants. E o way. Wait on, then Probably it will be completed. We should just end by saying that not only is destined come with the camera, but he also came and brought me to presence. He brought me a periodic table sour curtain. I'm not quite so where I'm good toe. Hang it. Brady thinks I should put it on the window behind. And he's also brought a fantastic tie, which says removed before flight. And I'm not sure whether I should wear this when I'm traveling on airplanes. Well, perhaps I will wear it in one of our videos. So watch and you might see when I'm wearing it. That's awesome.
