You may never have to breathe into your hand again.
Tired of wondering how bad your breath really smells sometimes? Researchers have developed a tiny breath test that can detect bad-breath bacteria in your mouth.
Researchers at Tel Aviv University have created the OkayToKiss kit. After placing a small amount of saliva onto the window of the device, a blue result lets you know to grab a toothbrush. If the results come out clear though, you are free to kiss whomever you like.
“OkayToKiss will turn blue if a person has enzymes in the mouth produced by the Gram-positive bacteria,” said Mel Rosenberg, a scientist at Tel Aviv University. “The presence of these enzymes means that the mouth is busily producing bacteria that foster nasty breath.”
Scientists believed that gram-negative bacteria breaks down the proteins in the mouth and causes that nasty-smelling breath on people. However, researchers on this project found that gram-positive bacteria also aid in stinky breath.
The OkayToKiss device is disposable and about the size of a pack of gum.
So the next time you are going for that all-important job interview or nerve-racking first date, pick up this product to make sure you are leaving a positive impression.
