Came to read about grinders; fucked combustion
This thing is fucking good.
The kind of people who smoke 10 times the material to get less high.and think that people that invest on that are fools and thats money better spent on herb.
By any chance did you notice how much I shake?
I have exactly the same concern... I wouldn't use tin foil by any means.Yeah the aluminum foil made me cringe a little too but simply using it to suppress the cool air intake isn't going to heat it up to dangerous levels IMO, but I still wouldn't use it personally. It's not the same as the kids I remember in high school smoking out of a pipe they crafted out of foil, yikes that was nasty and dangerous.
A 16mm borosilicate test tube would be a nice 'cap', then only torch the outer test tube(even better heat retention 4-5 draws) and u have got a 70% vaponic clone (reverse flow effect). Have built some myself works pretty good and very cheap (under 1$ ), but still searching for a perfect cheap and easy solution to hold the test tube in place (eg cork or matches work)...I think the best plug might be a 2 mm thick glass lid/cap that slides onto the hot end of the glass immediately after heating; maybe 1-1/2" long. Not only would it control the air flow but it would also insulate the hot glass, thus decreasing heat loss and protecting fingers. By forcing air to contact the hot glass twice as air follows its path, this would kind of recycle the heat, or use the heat very efficiently. It would also make the air path entirely glass (excluding the screen).
