The bulk of the sealing will need to be done where the pen tube touches the water bottle. If you’re using glue, spread a generous amount around the edge of the pen tube where it enters the water bottle. Let the glue dry for a few minutes to ensure airtightness. If you’re using silly putty, press the putty tight around the pen tube and water bottle to form a seal. Tape can also work if you have nothing else.
Push the small end of the socket into the hollow pen tube. It should be a pretty tight fit. Next, insert the end of the hollow pen tube without the socket back into the water bottle. There’s your rudimentary bong. But hold up there Sparky! We’ve still got a few more steps to go before we’re through.
With the pin or needle, poke a hole toward the top of your water bottle of choice. This will be your carb hole. Next, take your pen with the ball point end still intact, and push it through the hole to make it bigger. Remove the pen from the water bottle and pick up your pin or needle again. Your carb hole should be high enough that water won’t slosh out when you tip the bong.
Make another hole in the bottom third (toward the bottom) of your water bottle. Then push the pen through like you did with the first hole. That creates an opening just about the right size for your stem (next step) and helps keep everything more airtight. Don’t worry if the hole isn’t perfect, we’re going to seal it later on. Pull the pen out of the water bottle and move on to the next step.
Both the plug and the ball point can be removed with a pair of pliers. If you can’t find a stick pen with a plug in one end, you can always cut the sealed end with your scissors. We still recommend pulling the ball point end with the pliers but you can cut it in a pinch. Just remember that there’s a tube of ink in there and it may make a bit of a mess. Plan accordingly. Once you’ve removed both ends of the stick pen, you’ll have a hollow tube to use as a downstem.
You may also need to seal the socket/pen tube interface as well. Keep in mind that if you glue these two pieces together, you won’t be able to get them apart again. That’s why we like silly putty for all our sealing needs.
Any 16-ounce water bottle will do. Some of the water bottles out there are pretty flimsy. We like a water bottle that is a bit thicker so we don’t have to worry about squeezing too hard while we’re smoking. Remove and discard the cap unless you’re going to reuse this homemade bong for some reason.
A simple, cheap stick pen works best in this situation. We like the kind with a plug in one end and the ball point at the other end.
Once you’ve got your socket, find a piece of screen. This screen is to keep your bud from falling into the downstem. The mesh needs to be fairly tightly woven so burned bud doesn’t fall through. An easy DIY solution to this problem is to unscrew the tip of any faucet and remove the screen. Cut the screen to fit the large end of the socket. The nice thing about this step is that once you’ve got the screen in there, you really don’t have to find a new one for a while. You can remove it to clean now and again (if you feel like it), but, really, you can just leave the screen in there all the time. It’s not like you’re going to actually use it for its intended purpose any time soon.
