HYDRATED WATER BEADS ARE THE FILTERS YOU NEVER KNEW YOU NEEDED Experience the ultimate chill with YippyGroove water bead filters. They act as filtering screens in your water pipe to filter and cool down the smoke. It's absolutely essential that you hydrate these beads for at least 8 hours before use or overnight. After that, just pop a few hydrated water beads into your piece and get ready for a totally chill and far out experience! Notice them getting a bit dark and dirty? That's great news since it means they are doing their job, which not only makes for a better smoking experience, but an easier clean up too! Just toss them and put some new beads into water to prep them for their turn in the bowl. YippyGroove water beads are the way to a cooler, smoother, and cleaner draw every time. They come in a rad Limited Edition StashTin that keeps them safe and prevents breakage so you're ready to chill anywhere anytime. They are also just fun to play with, so enjoy them however you like.
