I have thought a lot about the basic idea of the replicator and sonic shower technology. The replicator as it was explained creates food and other things from matter storage. My thought about the basic principal of that is the ice cube and its atomic metamorphosis into water upon heating up. Then that same water through heat and wind friction physics vaporizes into a gas. Also mercury has some of these elemental principals existing as a solid and liquid. This would be the start I think to the research for actually inventing the replicator. The next step may be to apply that with the aforementioned elements and their forms to all other things composed of matter. Next the sonic shower. The sonic shower episode where it goes haywire and had to be repaired because of the screeching noise was entertaining. The sonic shower was shown to be a wavy silky translucent mist that cleans you. Micro cellular exfoliation is what I call it. In auto shop class in high school I used a silicon and sand blaster machine that made a rusty brake drum look restored and useable. It took bits of silicon and sand with high pressure air constantly chipping away all the fine particles of rust. Some soaps have little specs in them to help scrub dirt and dead skin. If there was a way to reduce the size o f a fine solid like sand so that through sonic speed air passes over the epidermal layer called skin removing any dirt or dead skin cells then it would be achievable to have a sonic shower. Discuss!
