bongoooo

petg water bong. i used petg translusent teal from bambu.

If you want it more clear just slow it down to 20mm/s and turn all cooling off. 

I highly recommend using a silicone o ring to get a better seal around the downstem and to ensure you wont melt the plastic. unless you are passing it between ,multiple people or taking multiple hits in a row it should not get hot enough to have any negative affects. As always use at your own risk.
