kiss o meter
This is a small sized (only 4,5cm x 1,9cm) gadget which has practical application on a date because of its discreetness.

The kiss-o-Meter is a handy device which  checks  freshness of our breath thanks to the five-degree scale: “kiss me”, “permissibly”, “possibly”, “risky”, “never”.  After ’ examination’ the appropriate diode switch on.
