Screen shows Evolve 2 graphic University of Wisconsin-Madison College of Engineering EXPO 2005 Grade school students and EXPO Exhibitor countdown: "Five, four, three, two, one!" Background music starts that plays for the entire video. A composite of scenes from outdoor activities at Engineering EXPO 2005 is shown: Visitors standing outside the Engineering Centers Building, engineering students changing a tire on a College of Engineering competition vehicle, a close up of the Maquina Fountain and visitors being sprayed by the fountain, catapult and rocket launches. Just before one of the launches, an EXPO Exhibitor tells students, "I need everyone in front of the rocket, please." Then, some indoor events are shown. Grade school students watch College of Engineering students show examples of water vapor, grade school students throwing their balsa airplanes at the camera, kids playing with motorized vehicles, and an overhead view of all the exhibits inside the Engineering Centers Building. Chis Wegener, School Outreach Chair, speaks with kids yelling, and other noises of EXPO in the background. "I didn't really expect all the 1600 kids to come and spend 90 minutes, but we handled it all right. I mean, it got a little hectic in there and it's just something we gotta learn from for tomorrow. We'll do a whole lot more with being organized tomorrow trying to get them through. And it also helps when you're dealing with a little bit older kids (he laughs). So tomorrow should run a little bit more smooth, but you just gotta think on your feet you gotta do as much as you can to keep things go smooth." EXPO Exhibitor yells, "End timeout! One minute and twenty seconds left!" Whistle blows. A composite of scenes from indoor activities is shown, including kids controlling carts and computers with remote controls. Mark Street, Robotics Chair, speaks with kids yelling and other noises of EXPO in the background. "The big thing that's becoming clear right now, is that it's not going to go as planned, and you need to have many layers of contingency plans for if something breaks, here is what to do. And so I am sort of formulating those contingency plans as we go, and we'll see how they turn out, and how they work out." Grade school students and an EXPO participant countdown the numbers to end an activity: "Five, four, three, two, one!" Whistle blows. Mariana Kersh, EXPO Co-Chair, speaks with kids yelling, and other noises of EXPO in the background. "It's been a real challenge as the Co-chair. My Co-chair Jesse and I, we lead a group of fourteen people, helping them do their parts. It's been a difficult process to not have your hands in everything. I've had to learn how to delegate, how to trust, you know, my team members to do what they need to do. And learn how to help them, but I can't do everybody's job. I can't put my hands in everything, otherwise I'd drown in it." EXPO Exhibitor (Hear a buzzing noise.) "What's happening here? There's these things in your muscles called proprioreceptors. And what's happening is when you're standing there, they sense your position, the positions of your legs. And so when you start leaning forward and they stretch, it senses that, and it sends a signal to your brain to compensate to keep your balance to make you fall back to earth, or at least correct backwards. So what we're doing is, we're stimulating those proprioreceptors with just a vibration. So when you're sitting there with your eyes closed, muscles relaxed, it makes you feel like you're falling forward and they're stretching, but really you're not, so you compensate and you end up falling backward." More scenes are shown from both indoor and outdoor activities. A powdery material is thrown at a blackboard, Bucky Badger signs autographs, and visitors view and sit inside future cars. EXPO Exhibitor "You see, it just broke into two pieces. There's a piece right there. Okay. Now what we're going to do, we're going to take this graham cracker, put it down into the liquid nitrogen. And what we're going to do, this is a little more dangerous so we'll take care of it, but we're going to chew on this. And it's going to be really cold in our mouths, so cold in fact, that all of the water vapor in our breath will become frozen. And if you watch our faces you can see the effect." It looks like white smoke comes out of the mouths of the two EXPO Exhibitors. There we many oohs and ahs from the crowd. A boy in the crowd says, "Dragons." EXPO Exhibitor asks, "Are you guys ready?" The kids answer, "Yep." Nicole Cuellar, Public Relations Chair "I actually didn't come into this position wanting to be the Public Relations Chair, but it turned out to be a great experience. I've learned how to deal with people, how to run my own committee, how to call people up and promote an event that I'm really excited about. I think that's been the greatest challenge, but also the greatest reward." You see a pit crew working on a car. Mariana Kersh, EXPO Co-Chair, "I just thought this is so huge, and so big, and I just knew I had to be a part of it. And I really wanted actually the challenge on a personal level, of trying to put a program like this together. And I just saw the magnitude of it, and it just seemed like such an incredible challenge. So I went for it." EXPO Exhibitor "It's a project to make a remote control for an iPod that uses motion instead of your fingers to control it. I got sick walking around during winter and always taking my gloves off, reach in my pocket, taking the iPod out, dialing it up, pushing the buttons. So I thought it would be really great if I could just use motion, like waving my arm or tilting my head to control it, instead of pushing buttons. So that led me to this, which has a small sensor on it which detects motion, and then another chip which interprets it. It sends a command to the iPod via the port on the top of it where the remote control normally fits in. So this is what it would be like in real life. And then for the EXPO, I mounted the same exact chip on a ping pong paddle so it would be easy to manipulate by people. And on the computer screen it's showing what's going on, on the chip itself, as opposed to actually hooking it up on the iPod. It's easier to see the logic behind it. On the left, there's a rectangle that represents the angle of tilt of the ping pong paddle, or the sensor on the ping pong paddle. In addition, the right shows the flow of the logic." Two EXPO Exhibitors EXPO Exhibitor 1 "Just crack into pieces." EXPO Exhibitor 2 "I can't even stretch it like it normally would. And if I warm it up for a second. It returns right back to its stretchy self." EXPO Exhibitor "This was a competition at our national conference. And the objective is to design a model plane or a glider, out of balsa wood, one sheet of balsa wood. This is the glider that we built after the conference. And we tested this in the Engineering Centers Building, and it went around eighty feet." Students throw balsa airplanes at camera. Shows people in the EXPO Office. Stephanie Budijono, Indoor Logistics Chair "I guess the role of indoor logistics is very challenging, yet attractive. So I just liked to take up the challenge, and present my best to the campus." Visitors in the audience say, "Oh," in amazement. EXPO Exhibitor "Now, as you can see right here, it’s actually liquid air. This is liquid oxygen that is sitting in there, boiling at room temperature it's so cold." EXPO Exhibitor "This here is a hybrid rocket engine. Basically,a hybrid rocket engine is a combination of a solid rocket engine, and a liquid rocket engine, in the sense that is has both solid fuel and liquid fuel. For the case of this specific engine, because it's a demonstration engine, the solid fuel is an acrylic rod, of plastic, and the liquid fuel is oxygen. What's gonna happen, is when we start this, The propane through a blow plug is going to ignite the ignition chamber up here. From there, high pressure oxygen will be flowing down through a whole in the middle of the fuel rod. And at that higher temperature and pressure, the oxygen and the acrylic will ignite and burn, producing thrust." Child in the audience asks, "So you're going to fire something in the air?" EXPO Exhibitor "So what we are going to do here, we are just going to turn on the fuel. I need everyone in front of the rocket. Have to make sure things are safe. I need everyone in front of the rocket, please. Okay. This is going to be really loud, so, you wanna cover your ears." The kids in the audience cover their ears and count, "Ten, nine, eight, seven, six, five, four, three, two, one, blastoff." There is the noise of the rocket blasting off.
