So I just made this today, and it was actually pretty fun! Got to eat a bunch of fresh coconut and now I have a awesome, airtight chalice with a glass airway and a slide. My only compromise was using gorilla glue to strengthen the plumbers putty as a sealant, and as you can see it does not look quite as natural and rasta as I had hoped. It works great, and will last me a damn long time. This is not your average water bottle bong! Also this will double as my new dab rig since it's way smaller and easier to use than my bigger bong
