When YouTube channel Machina decided to fly out to one of the top disposable vape factories in Baoan, Shenzhen in China, they were in for a shock.
While there, they found out how factories are able to mass produce vape products, from their inner workings to their testing process.
But it was this last section that was the strangest.
In the video, you can see the various testing stages the disposable vapes go through.
First, there is a pressure test which pushes pressure from the bottom of the vape to allow it to release vapor from the mouthpiece.
The second, is a suction tube while pulls vapor from the vape, kind of like the way a person would take a hit.
