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. 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. 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. Once you’ve removed both ends of the stick pen, you’ll have a hollow tube to use as a downstem. A small socket like this might not be easily found in some homes meaning you’ll have to buy one. That’s not usually a problem during the day, but when you’re in need of a bong for a late-night toke and everything is closed, you’ll be up a creek without a paddle. These sockets are pretty cheap ( $3.00) depending on which brand you buy, so you could purchase a few and keep them in various places so you’ll always have on handy.
The 7/32 socket has one small end and one large end. The large end will be the bowl and the small end will be attached to your downstem. 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. 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. Push the small end of the socket into the hollow pen tube. Next, insert the end of the hollow pen tube without the socket back into the water bottle. We’ve still got a few more steps to go before we’re through. An airtight seal (or as nearly airtight as possible) between the socket and pen tube, and the pen tube and the water bottle, makes smoking with this bong so much easier. This is where the glue or silly putty comes into play. We like the silly putty because it can be peeled off and reused after your smoke session. That said, glue or super glue will work just as well but can’t be reused (nor can the pieces be disassembled). 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. 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.
Fill the bottom third of the water bottle with water until it covers the bottom opening of your pen tube. Pack the socket with a strain of your choice, light up, and smoke away.
Homemade bongs can be fun for parties and when your regular paraphernalia isn’t available. But for regular smoke sessions, a glass bong is best. You don’t have to worry about whether everything is airtight or whether it will work correctly (it’s designed with both of those things in mind).
