So, I get a grapefruit to us as a pipe (to smoke in my room). I'm smoking having a good time, and then after about 5-10 minutes, my dad walks in my room. Thinking quickly, I took a massive bite out of the grapefruit. The problem is, the grapefuit obviously still had it's skin on. I gagged, and then coughed for like 2 minutes. My dad knows I smoke, and just shook his head and walked away. I am still pretty stoned, and my hands are shaking so I'm not typing well. Pretty hilarious (to me at least)
Desperate times call for desperate measures.... You can make it work, you just have to keep the hole open and clear. When I was smoking through the grapefruit, I had a piece of LIT ash fly into the back of my throat.
IMO- it would be easier (and less painful, lit ashes? ouch!) to just make a quick bong from a bottle. You could even skip the complicated water part and make an akward pipe. all you need is a bottle, a knife or something sharp, foil, and a rubber band or hairtie. Presto! Pipe-thing! Im sure theres a better name for it... but im way too high to think about it. As long as you get to smoke, right?
