how about a gas chamber ✅
warning: this is deadly!
(you need two glasses for this) I believe it is half a shot of tacquila, half a shot of strong vodka, set it on fire and pour the drink into the other glass - when finished pouring quickly cover the now empty glass with a beer mat (this will trap the remaining gas from the alcohol being on fire)
once the person swigs back their shot, you take the beer mat off and the person sniffs the glass content (the gas)
Discos - I absolutly hated it, my friends are obsessed though 😬
