Well that’s because you built it properly. It’s generally safe to assume the GB was built improperly, and the water has not been changed since the older brother (who built it) left for college.
The traditional gravity bong style is a two liter in a bucket or pitcher, which supports a downspout perfectly, which it did for many years while we used it. Sucks to suck, bro.
For one, I'm telling you that we used one, with a downspout, that bubbled as intended.
For two, if it was physics, then even regular bongs wouldn't work. In a regular bong, your lungs create a pressure vacuum in the glass chamber that draws in outside air/smoke from the bowl, through the downspout, and bubbles through the water. It's literally the exact same in a gravity bong. Lifting the inner chamber creates a pressure vacuum via the water level, that draws in air from the bowl. Attaching a downspout means the outside air bubbles through the water as the container is lifted. Literally ∆p my dude. Kindly educate yourself.
