whats good in the city ! im here to make some friends and further educate myself in greenery. I hope to bring something to the community and my first step is showing you a great way to conserve cannabis and get extremely high. its simple to make and im havent seen a post for this so here i go .. MATERIALS: sober bottle,apple,nail, hammer. on the side of the sobe bottle towards the bottom there is a spot where the glass is weaker than the rest of the bottle. its like an indent sort of. you take a nail and hammer the indent and it will break through fairly easily making a perfect hole. you then take your apple and slice it in half horizontally and poke a hole from the top through the bottom where the stem is. you basically made a effective waterfall gravity bong from grocery store materials.
