Any shroom growers in the house know what these are, if you dont its basically a glass test tube with a rubber top that you can suck the air out with a syringe(again the shroom growers have these laying around).

Anyway just curious if freebase dmt would keep good under negative pressure in a test tube?

What about dmt salt?

Would it be ok to put said tube in freezer or would a drawer or box be ok?
