fizzy drinks and carbon dioxide

[groovygirlie]

when i was about 10 and i had finished a fizzy drink i used to inhale the left over carbon dioxide or whatever in the empty bottle and it used to make me feel really weird. Sorry its so random i know!

Just wondering why, how, what actually happens etc. i dont understand it!

you're starving youre lungs of oxygen by inhaling carbon dioxide

I do it all the time LOL

and then you started sticking cigarettes up your nose and trying to inhale them

Luckily someone said you should light hem
and this then caused problems as a lighted cigarette up your nose......
