Here is a simple but effective homemade butane extractor that I made using a 600ml pepsi bottle.
First! All the parts you need!
Soda bottle. I used a 600ml.
Re-usable coffee filter.
Paper coffee filter.
The pic is pretty self explanatory! I used 3 screens overlapped, could probably use just 1-2.
You can see the cap has a few small holes in it! I taped the lid once I filled the bottle.
I tape the paper filter over the lid and for good measure!
Small hole on bottom of bottle for butane tip!
