In the future, refrigerator doors will be made of a transparent material that can expand to four or five feet and be able to contract to three inches (length-wise, in this case), one sheet of Material for the freezer and one for the lesser one. One would be able to see what was in one's refrigerator without having to open the door, saving electricity and the boredom itch (the itch one receives that persuades one to check the refrigerator during television commercials to see if any new food has arrived within the past ten minutes that might satiate hunger brought simply on by the fact there is nothing else to do). Inner lights open upon sensing body limb (infrared warmth) within specified distance. Perma-lights open upon touching a panel (on the side, I imagine).
In the future, unattached carpets pull unwanted spilled, splattered, and spunky substances through the visible carpet into a layer underneath, breaking the substance into a vaguer form during the process. The layer is removable, disposable, and biodegradable; removed much like one peeling away a sticker. Replacement involves the careful process of aligning the replacement layer back onto the carpet bottom, which I am sure will be made into an easier process in the future.
In the future, dental floss containers will remember the length of the first pull (able to be reset a couple times through some ingenious interface, as comfortable within usability). The inner spool that all the floss spools around contracts to some mathematical formula so that micro-containers of tasteless and edible dye would be able to inject markings in one try that would from further on indicate the aforementioned length of floss (it would mark off every six inches, for example). This would prevent the floss-er from ever having an uncomfortably short amount of floss or a wastefully long amount of floss, effectively entering the floss-er into floss nirvana.
