I used to be friends with a couple of potheads that were also engineering students. They were named Seth and Ro, and they were both genuinely hardcore about building things and makign them better. They wanted a bong that improved how much THC and the actual cannabis you get. They felt they could improve the lives of potheads everywhere. They liked to build bongs and pipes. So while they started out genuinely easy, they became more and more complex over the years. These were smart guys, and smoking cannabis unlocked the creative side of them, which they used to build more astounding bongs. They really did come up with some cool shaped, and better working bongs. I got one as a gift that I still use today. The weirdest thing to me was that they didn’t entirely care about the quality of the cannabis they smoked. They would buy the cheapest ditch weed marijuana, because their focus was on the bong, not the weed. They were genuinely great with letting me use their creations, but of course I typically used my own cannabis. I have standards, and I don’t mean I have to have the top of the line sativa, I just mean I don’t want garbage weed filled with stems and seeds. These men smoked the worst weed, and that stuff gives me a headache and that smells. Those guys taught me a lot about the physics of gravity bongs, and hopefully I taught them a little about the benefits of smoking better weed.
