foreign [Music] [Music] [Music] hey yeah where'd that come from I don't know but I'm sure it wasn't that the other day I would have seen it well let's check it out [Music] [Music] something we're using for houses well it doesn't look strong enough for that [Music] it is a pile of junk sure that's a great idea yeah but who's gonna pay for it they think we think we could no me either or somebody have to do his attacks around well it's worth a try let's go [Music] 55 that's the place shout out see in the window well come on [Applause] this is the place all right [Applause] can I help you we were just over at the daycare center we saw the things you guys built or the dumb side you like them yeah yeah you want to build one well it is not just that simple but why don't you come to the front office and we will talk why you want to build one okay we go to the song makes empty lattice from his plan and be more fun too and make him look much better than it does now well that looks like a good start um okay I think we could help you so you gotta learn a little basic law house first okay this is the uh this young plus over here that would like to learn how to make a dome the person who's going to teach you yeah domes are mainly based on angles does anybody know her name is not me right here's these two pieces of wood somebody's nailed them together now they say this is an angle it's 180 degrees it's one line and half of this angle would be 90 degrees the angle is the measurement from here to here right where the two lines meet okay have you ever seen this angle before then I can right that's the same angle 90 degrees uh where else have we seen these angles buildings the buildings right just like the building that we're in it's got the base and the side what happens when you push it go ahead try it okay so it collapses yeah but if they have four sides would be more like a building it'll be stronger okay you may be right let's find out [Music] okay so now looks more like a building right now what what do you think would happen if we push it again from one of these guys see ah the square is weak so maybe if we take one piece of wood out we stay with three it'll just be three angles then we'll see what happens okay one less board one less nail that makes less material now we have three sides and what's that what's that called triangle right now let's see if this is strong okay so it's strong for you to try it why would that be stronger than the other one the other one had four pieces of wood because it could take the pressure more evenly the triangle is where Dome begins tomorrow if you could make in the morning we will put you to work all right yeah okay we measure our pipes by cutting two guides we measure ten pipes at a time as the pipes are being measured they're transported to the cutting section once the pipe is cut it goes to be flattened in another machine that we have which is a kick press the reason why the pipes are flattened is because they have to be bolted together and that's done after it's drilled which takes us to the drill press and once all the pipes are drilled then we're ready for color coding the reason that we color code the pipes is because we have three different lengths and sometimes the lens are similar to one another and when we're cons when we're in the construction we have to know which pipe goes where when you're going to start assembling you have the person that is the supervisor what he does is he begins the assembly by laying out the first five pipes which form a pentagon which consists of five triangles after these pipes are laid out the people the workers will then bolt them together once each level is bolted [Applause] then comes the part of tightening it up after a little while a little work your Dome is ready for any kind of use you have in mind you can use it as a tent as a tool as a toy anything you want to
