This Australian kid.
Kids or "ravers" these days tend to use nose inhalers like 'Vicks' or the Thai equivalent 'Poi Sian' where sniffing them essentially enhances their drug high. I'm not even sure if this is a common thing outside of Australia to be honest.
But what this kid was attempting to achieve was actually placing the liquid part of the Poi Sian IN HIS EYE (He outlined this within the comments) - the worst thing is not only are you blowing a menthol alcohol substance into your face, it is also blowing his bacteria laden salvia into your eyes. Obviously things are going to go wrong
