When with friends, I always use a bowl, which is fine... but when I'm by myself, I like to be creative and make bongs. Well not really creative, i usually just use a gatorade bottle with a sharpie in it... then add ice/water and i'm ready to rip. Right now I have 2 bottle bongs that i've been using for well over 6+ months... they are kinda gross looking but whateva.

I also love the gravity bong, but I only use it when I've got lots of schwag to burn.
