It took me about 5 minutes to build, including candle set up and hanging as well as bending a holder for the glass jar out of a coat hanger. I am inclined to use my hands well, but still...

Anyways, how much herb did you put in, how fine was it broken up, and how big of a candle flame did you use?

I used a few small nugs but a shitty candle, and I think if I ground up the herb first and used a hotter candle it would work *a lot* better for me...
