 Okay, at zero hour four five minutes that test point should be delta one zero two zero one five Charlie. You do not need an F4 and you need to start at hotel dot four which is on page NOM 28 with a new test point. Okay copy that. I'll be doing test point delta one zero two zero one five Charlie. I do not need an F4. I'll start with step hotel dot four and I'll be using a new test point. That's good copy and I have the information for the one at one hour twenty three minutes. Okay we got a big crowd watching up here. And we got a big crowd down here watching the big crowd up there. Chance to change your mind but it looks like we're done with the height setting. Not a problem. Let's go space out some THT together. Quite flush. I got Roger over here to help me out and we worked it a little bit together but to pull it apart the base connector has some red marks on it so it's a real tight fit. And it's just like a paper thin gap. It's just not quite perfectly flush. It's as far down as we can get it. Is it okay to just leave it like that and see how it goes? Yes THT says that gap is expected. Thanks for noticing. The experiment called the bubble drop and nonlinear dynamics. And what we're looking at here are levitating a drop in an acoustic wave and then exciting that with another sound wave and watching the decay of the vibrations as we go along. You can see the bubble on the I mean the drop on the TV screen there and you can see it vibrating a little bit. So the vibrations are being induced by sonic waves or sound waves and there's a computer over to Don Dryke there panning around Nandisee. And on that computer you can see what will look like final sort of waves or waves that are regular oscillations. And this is Don recording the data and helping the PTSD to record that data for the PI when we return. A large number of combustion experiments on board. This is one of our SIT experiments that's studying how SIT is formed. This is a ethylene flame burning. You can see the flame in the top of the monitor in the center there. Gretlin Terrace was so interested in watching this stuff. He came back from getting ready to go to bed and he's hanging in there helping me. He's upside down because that's actually the orientation of the flame. The flame burns from the top of the monitor down so he gets a better view of it that way. And he and I are consulting on the shape of the flame. We do have some adjustments on board that can let us real-time adjust how that flame burns. Okay, I guess I'll talk about this one. This is Gretlin Terrace PS2 demonstrating how you wash your hair in space. Now what he had known as hand is what we call rinse-free shampoo. It actually works very well. Everybody has different style. Greg likes to heat up water in the galley as you see him holding the water there. And he puts the water, combines that with the rinse-free shampoo. It would run down your face to be a real mess, but in space because there's no gravity, it just kind of hangs there in your hair. You see him using the towel there to towel it off. And it absorbs in the water. So much they do a lot for family support while the crew's up here on orbit. This is an example of me talking on the subtle amateur radio experiment to my mother this morning. I got to wish her a happy 4th of July and family reunion today she's going to. So that was a real opportunity for me to have a contact with the family back home while I'm up here. Okay, this is me with the GBA experiment. And this is basically a small greenhouse that we supply in space to grow plants. And there's a couple of reasons scientists are interested in that. One is that in understanding plantivity, they can better understand the physiology of plants that could help improve plant production on earth. The other reason is that eventually as we do longer missions in space, we're going to have to grow plants and take our food with us. The other neat thing about this experiment is it involves the express rack, which is a modular rack system that we'll use to change that experiment on space station. This is our chance to prototype that and figure out how well it works before we fly it on space station. Actually, Susan and Don took that experiment from the mid-deck and transferred it back to the space lab in this rack. If you would accidentally cut yourself a microgravity with your blood clot like it does here on earth, and you may be aware or less that we do study the immune system up here. There's some data that shows the immune system works a little bit differently in space, but the clotting system, as far as we know, works exactly the same way. And certainly when we get minor cuts, as I actually impact currently have on this finger right now, they clot up just fine and normally. The one thing that is a little different in space that I've noticed over my four flights is that you don't have your hands in and out of water all the time. So sometimes the cuts don't heal quite as fast because it's harder to keep them clean. You don't realize how much cleaning you get by accident on the ground that you don't get up here in space. Okay, I guess I'll do the next question. This is the first time that we've taken internet questions on the computer, so I'm looking across the cockpit at the computer screen, and this one is from Jim Roach from Kerry, North Carolina. He asks, being in a controlled environment for a prolonged period of time and breathing a prescribed percentage of inhaled oxygen, do you periodically run blood gases on the crew to determine if they are maintaining proper oxygen saturation levels? And the answer to that is that we don't do that routinely. However, on my first mission, there was some concern from data from the Russians that our hemoglobin oxygen saturation decreased following spacewalk, and we did a spacewalk and we carried the special instrument that we used as soon as we came back into spacecraft, and we determined that we basically had 96 to 98 percent hemoglobin oxygen saturation, and so that answered that question. The next question that Roger's going to answer is from Zachary S. in Kissimmee, Florida. The question is two questions. How does it feel to be in zero G, and do you have a fireproof room to do these experiments? I think the answer to the first question about how does it feel to be in zero G depends on what day you ask me that question. The first day, it's a little bit different than being down on the ground, but the more days you're up here, the greater it is, and then it's worse. It's absolutely fantastic. It's almost like being in a swimming pool with no friction. You're on one side, you push off and you glide completely to the other end of the pool. And that was always a desire and the race we used to have when I was a child to see how far we could glide. And up here, you could glide down forever, almost, it seems. The second question is, do we have a fireproof room for the fire experiments? And the answer is, it's not really a room. It's a small chamber. It's about eight inches on the side or something in that dimension, about an eight-inch cylinder, and it's surrounded by another layer of steel so that there's no danger of an explosion at worst. And so it's absolutely safe and the fires are really small in any case. So there's not any real danger to these things at all. And Roger, if you could, we are getting some reflection and it's going to be hard, but if you could point to where you see the liquid, copy that and we see that.
