The surprising thing about the Twisty Glass Pipe, is that the obvious way to load the Twisty is the wrong way. Or the inefficient way, anyways. The immediate thought is to reverse the twisting direction and suck up the herbs against gravity. Don't get me wrong, this method works. The problem is that it is laborious. The space for the cherry doesn’t make things any easier, as you’re then required to have a constant mound of herbs to reach the screw.
This upward twisting action is the method used to load the first few tubes of ground up material. See a detailed loading instructions by 7-Pipe here
