That looks like something from Chemistry class
Ah...I still remember measuring the weights of reactants before a reaction and then measuring the weights of the products and then having to FUDGE all numbers together to get the results we were 'supposed' to get
Never saw any beeks using such a thing but it does give me an idea.
I'm not patient enough to get a smoker to properly smoke and I would LOVE to ditch those things for something faster. I might do a little experimenting with my push button propane torch (used for sweating copper pipes) and see if I can make some quicker, more reliable smoke this season. I seem to always run out of smoke at the most in-opportune times when messing with the bees. :'(
