Don't freeze them
Don't buy them. Go for plastic beads. These are nothing but a pain. You need to soak them 24 hours before use. Since they come so small and expand so much you can't tell how many to soak. So I soaked all of them. The description says you can freeze them. So I froze what didn't fit in my bong. Yeah well once they thawed they turned to MUSH. Great for a pool toy for kids, not for smoking.
