Can you tell me what you got here? First of all, what's your team name? Fire axle. Fire axles. Can you explain what we're gonna do? So we're gonna have we're gonna drop a marble down this inclined plank. It's gonna hit the car, which the car will roll into the Domino's with our stable and the dominoes will push the marble, the marble will roll down the inside planes, which will hit the car which will catch the car to roll and hit the dominoes, which will not cause the ball to roll. This figure out where we wanted to go from here. Push that turn. That car will push that marble and push over there. And then that ball will start. Come on. Breathe out. Gravity goes down to another. We want it down into there. But first, this is not like this. Gravity would pull it down there. That's why we had to take it to here. So gravity could change its direction and pull it on here. Tigers in motion. There we go. Come on. In the middle of the marble comes through the twist and come on in. Then it goes. The other two things. And then it comes to here. And gets in this. Very good. I'm coming. One got stuck with the other one. Finally gets that time and did it. All right, and what's going to happen? We're going to hit it. 5 minutes. All right, let's give it a try. Yeah. I love this. Very good. And can you in Megan explain to me what's going to happen here? So we're going to put it through here. It's going to go to the two. Gravity will pull it down. This is my plane. And the force will pull it down this track. We will try to make it go into here. Try to make a turn. So close. Perfect. The zooming girls, all right. And so what's going to happen, Caitlin? Careful? It's going to hit all those numbers. And then it's going to hit that car. And then goes through that. And then that thing will hit a marvel not normal people go to. All right. Wait a minute. The rolling wheels, Hailey. Hello? All right, you want to give me a countdown? Haley. Hi. Two, one. Here we go. Wild rollers. All right. And what's going to happen here? So the marbles will go down the ramp. What do we call the ramp? It's a new plane. So we'll go through here the pipe. It will hit knock over the jug. So there's highs that box to open. The car will go hit the dominoes, and the dominoes will create the marbles. So the marble will go to the cup. All right. Three, two, one. Okay. Ethan and lane, what's your team name? And what's going to happen here? Jump off. The ramp, and then going around. It's very good. And so what force is making this happen? Gravity. One. Okay, so the marbles will get tilted. They'll go through the loop. They'll go down their jaw. And jump down here. All right, let's do it, Julia. Maybe not. Whoo.
