I thought about buying water balloons to seal and clean my bongs. It seems that Resolution Caps improved on my idea. THE way to go to seal/clean your water pipes. Recommended

these things are awesome and I don't know why I didn't purchase them long ago. If you're anything like me and like to keep your glass nice and clean these rubber caps are worth their weight in gold, they make cleaning 100x's easier than before and they're at a highly affordable price point.

The two small caps fit nicely, but the big one is a little bit too large for the biggest opening on any rig I have. But it is quality stuff that does the job. A little pricey, though. It’*****-or-miss if this kit will fit your rig, but odds are you’ll be satisfied enough.

This tool makes cleaning a breeze quick and easy. Definitely recommend letting the caps fully dry between each clean. Thank you 420science for providing this great product.
