How to Properly Soak Water Gel Beads

  • Prepare a container and add plenty of clean water to fully submerge the water gel beads.
  • Soak them for 4–6 hours until the beads expand, soften and become fully plump.
  • Keep the beads completely under water during the whole process; otherwise, they will not be fully soaked and may easily cause jamming.
  • If the soaking time is insufficient or there is not enough water, some water gel beads will not absorb enough water, which may cause poor firing or jamming.
