idea for smell proof container?

I'm no scientist, but aren't odors are small molecules in gas form?? if so don't they travel from high pressure to low?
if so, wouldn't be possible to contain the odor if we had it inside a low pressure zone that is within a high pressure zone?

example:

got two sold Container A and B made from metals;

-Container B is smaller than container A and can easily fit inside container A.

-Container B is fixed in the center of container A(or the interior of container A is designed in a way that container B is rested and fasten to the center of it).

-Container B is depressurized to a point where it has negative pressure while container A is pressurized to the point any opening would cause the air to make a sound if it finds an escape.

If the weeds or seeds (that is sealed in a bag to keep it safe from negative pressure) are placed inside of container B would this set up prevent the smell from escaping and therefor becomes drug dog proof?

ps: I know it's not something easy to accomplish but it is just a thought

If you have a non permeable membrane, it's not what's in the container that is detected, it's what's on the outside of the container.

Check out Pelican's waterproof containers. If it's waterproof, it's air tight, which means its gas tight. Smell is molecules traveling in the air. No air exchange, no smell. Check it- vacuum sealed bag inside a mason jar inside of a pelican case... Not a worry in the world.

Snaps is right- wipe everything down with alcohol wipes.

that's a great idea Horse, but problem with that you can't place it in your pocket and X-ray will see through plastic a red color which points out to them it's organic. but I like the idea of having 3 air tight container set up, if molecule gas escapes it be microscopically smaller than it's original ratio.

The original idea isn't xray proof either. Although also a good idea.

EDIT Better not bust that technique out in public. ..

what about dogs?

I have flown a shit load of times, and have never seen a drug dog in a terminal. They are very, very rare except for cargo terminals, and only then in major ones. Wrap it in freezer bags, and shove it down your pants. Has worked for me for years

and send in glass ie ball jar..however, i've been know to take a 3-pack cracker jack box..empty and replace the contents from middle box leaving foil liner and resealing..perfect for a zip FYI..the better choice for wipe down is bleach..it kills everything.

i've seen dogs plenty..mostly in dallas airport in the terminals once you get out of search.

I have seen plenty of dogs at airports. But if you are not noticing the small mutts on strings, instead of a leash, you are only looking for attack dogs,

Great ideas. When travel I vacuum seal my stuff and put it in jars.
