IDEAS (a working list)
Modern Art Exhibit: A refrigerator, but covered in paint. Call it "Stainless Steel"
Entrepreneurial Endeavor: Mouthwash to completely replace teeth brushing. A few swishes in the morning and users are good to go, cavity-free
Restaurant: A haven for picky eaters, where you can order a plain sandwich without having to say "no sauce or vegetables, please"
Bar Concept: One with adequate restrooms in every corner. Hell, maybe it's a bathroom-themed bar.
~Patent pending on all of the above~
