Would blowing all of your hit into a big 2 liter bottle and quickly putting the cap on work for hiding smell? And how many hits could I blow into one? This wouldn't be for breathing the smoke back in later, but so that I could quickly go outside later and release all of the smoke from the bottle. So that no smell should really remain indoors. I feel like this is a great idea, but idk... Would it work?
This could work, but I think you would need a bigger bottle. I think that when I take a big hit, I could breathe out more than the bottle could hold. If you take really small hits, the 2 Liter bottle might work though. I could be wrong though, so I'd love to hear how this works if you try.
this wont work in its current form but heres an altered version of your idea: get a black bin bag seal most of the bags opening up with tape get some sort of tube, >5inches , anything really hose pipe, kiddy birthday party blowey things, you could even roll a piece of card up and make a tube. stick it in the hole in the bags opening and seal up it good. now blow your smoke into this bag that is many times greater the capacity of your lungs and weighs nothing and isnt as unweildy as a plastic bottle. its sorta like a volcano vaporizer bag but you blow in instead of sucking
