How to use?
If you have seen a bong, then you will notice that the down stem on some of he products is very high up or even almost sideways.
This is a design choice. As a Bonggle, being part bottle and part bong, you would fill the bottle close to the fill hole, but upon taking a hit, you are going to slightly tip the bottle back to allow the stem to be submerged in water, but not tipped enough to accidentally drink the Bonggle water. :)
