 Anybody guess what happens when you add octa-sensor with water? Anybody? No? No? You make something called carbon dioxide. You make another gas, and when you create something, it needs to go somewhere. It needs to burst and pop. So, sir, can I have you come up here, sir? You're lucky, aren't you? What you're going to do is you're going to put some water in here. I'm going to put some, and you're going to put the caps on and turn them upside down for me, okay? I like to get messy. We're going to get messy, okay? It's up here. Mom said it's clothes or washable, so that's fine. Now you're just going to put a little bit of water in each one of these. Ready? Now, top them off. Well, that's way too much. Okay, go ahead. Go for the next one. Okay, stand back, stand back, stand back, stand back. Stand back. Put a little bit of water in that one right there. Good. Stand back. Can we see that one last one? We'll do this one right here. We're going to do our last one right here. Right for the camera. Come to the camera. Smile. It's a little experiment that we kind of show for the kids. We get the kids very, very excited about science. The first thing I always tell kids is I'm not there to teach science. Your teachers are there to teach science. I'm there to get them excited about science. So, hopefully, this is one kind of thing that gets them excited about it. Thank you very much for letting me perform for you all today. And I hope you guys get to come see me sometime in the summer. Thank you very much.
