Meaning, the resin that's left behind after cannabis is smoked. I know it consists of tar and a few other things, but it also has a decent amount of THC. Having been heated already, has the THC gone through decarboxylation already? Or is whatever remains in the resin still inactive THCA?It's a weird question but this seems like the best category that I can get an intelligent answer for this on.
a creaking noise? sounds like it could be the struts or shocks (whichever your car has).
The night vision you are referring to is actually reflected infrared light. Almost all of these night shot capable cameras actually have IR emitters, which you cannot see with the naked eye, but the camera can. You see the eyes and reflective materials because they are actually reflecting the IR light from these emitters back into the camera. Military style night vision uses image intensifier tubes to gather and amplify the light available. They require some amount of light to work, hence the name starlight scopes. Even some of these have IR emitters for use in totally dark areas, like the interior of a building where you have no light at all.
Just wash it with a product from mothers and then wax it.
