Karaoke + sound + plasma + light

Karaoke is a popular way to pass the time. Singing is wonderful: it develops a person's self-confidence, connects it with others, gives a lot of pleasant emotions, but under one condition: you must sing together with friends or colleagues! The communicative characteristics of karaoke have been noted by psychologists. The process unites people, at the same time it is absolutely neutral - singing does not violate any boundaries. So no matter what, karaoke is very useful in all respects. People sing at home, at corporate parties, in bars and restaurants — everywhere.
