The water dies evaporate so you do need to refill the water. Someone on anther video said to keep it out of reach of children as these gels can get stuck in the bowel if a child or pet and it can be life threatening. Perhaps a lid can be made from a clear acrylic coaster? One that can be opened to add water but acts as a deterrent to curious kids & cats?
so to be clear, once you add water to the vase with the beads you can't see the outline of the gel beads anymore? I ask cuz I'm looking to have a completely clear look! Thanks!
