Because we're going to be doing a pretty awesome experiment with dry ice. Well, let's find out. So, I've got here a cooler... ...and then, I'm going to bring out bags of dry ice... ...that I just purchased from the grocery store. Some states don't sell dry ice in the grocery store, which is very surprising. Then I need to break it up. I got another couple pieces. Alright, that's about thirty pounds of dry ice. Alright, here goes- oh! Alright, here goes nothing! Woah, look at that! It is a bit windier right now, so we got all that smoke going away. Woah, look at that! (REPLAY) It is a bit windier right now, so we got all that smoke going away. (REPLAY) This is awesome, dude. So cool. I wouldn't swim in it, with the smoke, but look how cool it is. Look at that, so cool. Look at all that smoke. Wow. (Inaudible) Wow. (Inaudible) It looks like a volcano underwater, isn't it? Look how amazing is this, wow! I think this is definitely a success. Maybe a bit too windy, but it looks beautiful! Look at that. So awesome! (Inaudible) How cool is that? Amazing. (Inaudible) Amazing.
