The Russian Mr. Wizard would like you to suck on his fumes

As far as I can tell this is some begelled Russian Mr. Wizard showing off the production of mist from a melting piece of dry ice. While the mist is essentially carbon dioxide it’s probably not the best thing to give to kids. However, he does say “Nie boj sie,” meaning “Don’t be afraid,” when he shoots a stream of it into everyone’s faces, which suggests he’s been huffing this stuff for years with no ill-effects. Why? Триглав only knows.

Anyone speak enough Russian to tell us why this guy is offering CO2 facials?

Thanks, Alex!
