This instructable is for all those young kids that want to make a very large project but don't have enough space. It is also for kids with annoying parents that always seem to bust your secrets and catch you playing video games. And finally, it is for kids that are lazy that just can't seem to get out of bed. This rooms solves three problems in ways that are simple enough to construct.
Step 1: Space saving/hiding part 1
This is for storing (or hiding, whichever one you would prefer to choose) things that you don't need at the moment, like bookshelves, closets, desks, and more.
So the six red boxes on the top in a 3 by 2 grid are the things that you want to put away. The black strips and the blue spheres inside of them are conveyor belts. They move the boxes labeled A through F (the things you want to store) to hydraulic pumps, which move it down so you can use it.
On the third image, it labels the conveyor belts and the storage. Here is the path from storage to room:
Box A: To Conveyor belt 1, to 2, to 3, to 6 (hydraulic pump)
Box C: to C.B. 3 to 6
Box E: To C.B. 5, to 4, to 3, to 6
Box B: From C.B. 7, to 8, to 9, to 12 (hydraulic pump)
Box D: To C.B. 9 to 12
Box F: To C.B. 11, to 10, to 9, to 12
There is a ceiling under the conveyor belts, holding up the whole thing.
