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.
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.
