There was one episode I saw that has always been kind of a mystery. Adam (Nicholas) find an old shed in someone's backyard. They look inside and it's decorated like the inside of a spaceship, with lights and a moving scenery, like through a window.

Then the oldest brother tells them that it was a project he did when he was much younger, and he had forgotten about it. I don't remember much about the show, so here are my questions.

1. How was it still in working condition after so many years?

2. Where was it, and how come no one else knew about it? Was it hidden somewhere?

Thanks for any help.

Anyone?
