Does anyone know how to make a gasmask bong

I have a gasmask but idk what I can use to make the actual bong part of it, I have access to PVC pipes but idk if thts really safe for your lungs, I have no bongs or bowls but I can get some. Can anyone help me.. I need to know before this party I'm going to tomorrow night. Thanks ahead of time if I can't get back to you.

This nice young man named Laremy Tunsil probably knows.

Gas mask bongs suck! And they burn your eyes.
Buy a nice looking glass bong with a percolator and precooler , if you want to Impress people go for a (grace) bong there cheap and look cool . But not my suited brand.
