I have a metal pokey thingy that I use to scrape,clean, whatever else I need it for. Anyway, after a month or so, I take my razor blade and scrape off the resin and I have an excellent little resin ball to choke on, errr I mean smoke on.
That's sort of funny. When I was young I would do that, or filter the bong and dry it or shake out my drawer and smoke whatever fell into the corner.
I watch my kids scrape their pipes about once a week. I usually have some bud stashed away someplace, but they wait until they scrape the pipe before they ask lol. My kids are 20 and 22 btw.
