[pingpong]

Ok so swim had read the topics in this forum about nitrous and got the impression swim would be laughin or trippin

so swim went to the store n bought 6 cans of whipped cream n filled a ballon n tooted it blowin into the baloon and then inhaling in and out til it was all gone. swim felt it and ye it feels pretty good but it only lasted about 20 30 seconds if that n i didnt laugh n i got nothing to what iv heard about these n2onions (which sound delicious i mite add), so swim thought he wud buy a cracker n some 8g chargers, swim got crackin n put 2 chargers in a baloon and tooted it same thing happened but not as good as the whipped cream gas i fink,

is swim doing something wrong??
how much is needed to make swim burst into laughter or atleast get something other than i nice head rush?

and also does anyone have any information on nitrous and asphixiation because i get paranoid
