A partial, slight vacuum. I mean, it depends what you're getting at. An empty balloon placed on/over an empty bottle, then stretched out, may create a partial vacuum, or negative pressure, inside the bottle. I wouldn't think it is a good way to attempt DIY vacuum distillation though. Some people use a syringe for this type of DIY vacuum when making things like butane honey oil. Very inefficient though. In a lot of cases, there will be a bleed, a slight loss of product when vacuum distilling. I have a lot of expensive glassware I haven't got around to using yet.

BHO doesn't really need a vacuum though because butane is so volatile at regular pressure, slight heating will rapidly distill it off. The idiots making it though are too dumb to create a condenser to re-capture the butane, so they end up wasting it and purchasing more, letting it bleed off into the atmosphere which is also a lot more dangerous, since it only takes a tiny spark.

I'm all for DIY stuff as long as it's efficient. https://en.wikipedia.org/wiki/Vacuum_distillation
