Smell in Memory / Concept Watch

"Smell in Memory" is a watch which can rouse the specific memory through smell. There is a sampler on both sides of the watch collecting the odorant molecules as a chemical sample of the smell and transferring it to an array record bonded with this special time.When you turn back the time of the watch to a specified moment, the electrode inside will selectively volatilize the solid spices in the watch according to the array record. The mixed gas molecules shedding from the hole of the sampler can stimulate the olfactory nerve.
