Have you ever seen a cook sneeze at a restaurant or fast food restaurant? Some people may be worried that the saliva of the person in charge may be scattered and not in the food being cooked.
Many people will think, "Saliva ...". However, if the person in charge of cooking carries a virus that is transmitted through saliva, the possibility that a person who eats food will develop a virus infection is not zero.
In such a case, if you check the food with "Saliva Scanner", you can eat with a little peace of mind. It may be a relief, but it may be useful when a particular viral infection is prevalent.
Also, in old dramas and comics, there was a scene in the hot water supply room where an office lady put a rag of squeezed juice into the tea of her boss who didn't like it, or put saliva in it. For those who are worried that their tea is not treated that way, "Saliva Scanner" may be effective.
However, I feel that it is more effective to try not to be disliked or to make tea by yourself. ... By the way, the squeezed juice of the rag cannot be detected by the "Saliva Scanner".
"Saliva Scanner" is currently looking for investors on kickstarter. It smells a little suspicious, so I don't recommend investing.
