Welding or soldiering seams both have pores that, for the purposes of a dog’s sense of smell, might as well be a mile wide. Plastics with “low” gas permeability likewise might as well be fishing nets.
It’s hard to imagine the sensitivity of a dog’s sense of smell when using our own as a point of reference. Being able to smell things in parts per trillion if compared to our vision would be like us being able to see a pebble on the ground 100 miles away on the horizon. And this would be like someone trying to hide a beach ball in a mesh bag 2 feet away.
Fill canning jars full of material, seal the lids (heh) and boil in a water bath. Wait for it to cool, twist the lids on tighter to keep the seal on, there you go.
There was one comedian who suggested hiding contraband in a little dog’s bum. That way, the customs officers will think that the sniffer doges are just sniffing the little dog’s bum for the sake of it.
If a small amount of chemical can alert the dog by percolating through the wrapping, a small amount of chemical in the hair, clothing and gear of our hero should also alert the dog, even when our hero has no actual chemical stash with him, correct?
In other words, do we know the false positive and false negative rates of the dogs?
That is very funny but in reality that won’t work. Because the sniffer dog won’t only sniff the bum, it will also perform an action(usually sitting down) indicating that illegal substance was found.
As for the issue of transportation, don’t. Just grow it where you blow it. It’s just a simple plant, all you need are the non-smelling and very tiny seeds. Granted, you only want the female variety and they do also smell when they go in bloom. But you need green fingers if you want the green stuff, and carbon air filters. And if inside is not an option, just plant them outside at a remote area.
Should I have to do this ever, while keeping to a sort of house-hold practicality, I would likely vacuum-seal it using a common food sealer in an airtight bag. I would then put this bag inside another bag, filled with water. You would then wash this final bag in a series of solvents to fully clean it, leave it out to dry and etc.
It depends what you’re trying to get away with. You could fill the bag with something much more obnoxious than water if you want to mask the smell (and there are many things even a sniffer dog will avoid moving toward). However… if police found you with a bag full of butanal, they may not be best pleased.
Meanwhile, gas permeability. True, most plastics will allow some material through - probably enough to get caught. The water will slow this drastically. But if you camp out in the airport for a few years (resisting the urge to dip into your own stash) then it may come back to haunt you. Using a metallised nylon for your bags will eliminate this problem and can be bought at hobby stores
This invites the more devious plan of carrying a spray bottle with some dilute , ground canabis (or the vice of your choice) and spraying it on as many people as you can while walking around. The majority of the smell may/may not be coming from you directly, but I doubt that would matter if you sprayed people outside of the airport and let them walk in first. Do this for 10/20 mins, then enter. Then you can hide in plain sight.
That would involve biting a capsule in half, which is problematic. A twoie was the word for a tuinol, a very pleasant barbiturate for those who used to enjoy such things. We used to call them “reds.” The drug has been discontinued.
Possibly. But, I think we’d need to know the size of whatever molecule that will trigger the dog. But, I chose those three plastics as I know they have no permeability in regards to nitrogen, COH, and NH, based compunds… I’m trying to find the link now but can’t. I must have gotten the exact right search terms that first time around.
Any ways, something to think about is the size of our noble gases. If you can store a noble gas such as hydrogen in a container, which is our smallest element, then I doubt that the dog will be able to sniff anything in said container assuming a perfect seal. So, you need to find whatever molecule the dog is triggering on, determine its approximate molecular size, then find a container that can contain whatever gas is smaller.
I think that is all fundamentally correct. And to date, no such material or container has been identified that can serve a practical barrier for hiding marijuana from drug sniffing dogs.
The factors involved are the permeability of the material (which involves more than just porosity), time, temperature, and movement. Even the beaker you mention would eventually leak hydrogen with enough time, I think, but it might take many years.
In practical terms we can look at the question from another perspective: what do the professional drug smugglers use? In almost all cases it is paper-wrappingcoveredwith a low-permeabilityplastic wrap. Their hope isn’t so much to hide the odor from dogs which is logistically impossible but from people.
If there was a practical way to conceal the odor from dogs they would be using it. Maybe we don’t know of it because it is so effective none have ever been caught.
For much smaller amounts almost any truly ‘air tight’ container could theoretically work for at least a period of time if completely washed, washed again outside of the area where it was packed, then completely washed again outside of that area, etc. several times over. The more heat, or motion the container was subjected to the faster the odor would permeate.
But what you are basically saying here is that the molecule that dogs detect is smaller or more permeable than hydrogen. Unless by "no such material or container has been identified " you mean to say this search hasn’t been very thorough.
And I’m not sure I can agree with your quibble earlier about dogs not smelling “through” things. They surely do if the molecule is passing through a container.
