Pepper Spray

saw a bottle of pepper spray in ahThan's car
so ~~ hand itchy ...i played with it !!!
ha.ha. spray it on my hand and tried to smell it~~
nope ,nothing special...like dirty brown brown water only,
no smell at all ~~thinking whether is it expired d or not effective enough..
wipe away with tissue..
and 15 minutes later...
i can feel my nose is stuck and my face is hot hot...maybe smelling it that time kena my face or what ~
dun care 1st...
half and hour later..my hand become RED and HOT and PAIN !

but im wondering ~~
why ahThan keeping a expired pepper spray in his car??
30 min later only can see the effects~
it suppose to causes immediate closing of the eyes, difficulty breathing, runny nose, and coughing .The duration of its effects depend on the strength of the spray but the average full effect lasts around thirty to forty-five minutes, with diminished effects lasting for hours.
