well i made the standard perc with straws and 2 gatorade bottles, but for the stem i used a piee of pvc pipe on a 90 degree elbow in the side of the bottle. for some reason tho when i would take a hit, water would fall from the top chamber where the perc is down through the straws to the bottom after i would stop inhaling. i think its becaus the water rushing to fill the pvc pipe caused a type of siphon effect and pulldd the water thru the straws, but idk. if anyone was able to follow that and knows how to fix it help would be greatly appreciated
i dont have any pics but if u can picture just an L shaped pvc pipe in the side of the bottom bottle acting as a stem, and a perc on top
try not putting water above the caps if you do.. or, dont tilt the bong if thats what you do. only problems wrong with my homemade perc.
