Review on 💧 Upgraded 20,000 Clear Big Water Gel Beads for Vase Filling - Floral Beads Gel Bead, Water Pearls Vase Filler Bead for Wedding Centerpieces and Floral Decorations by Hannah Curi

I am writing this in relation to a transparent soil substrate for observing root growth so transparency may not be that important for decorations. They swell to 16-18mm in diameter in about 5+ hours. I first noticed that they are not a ball like some of the other beads. However, when fully retracted, they become mostly spherical and somewhat oval, which is not a problem as you can see in the photos. Clarity is "modernized", what could explain the oval shape? Photographs were taken with distilled water. A yellow was thrown for comparison, a full container of yellow balls looks like light yellow water. After complete absorption, the balls occupy 2/3 of the volume, 1/3 of the water. Despite other comments, they do NOT absorb food coloring. . Just soaking them in food coloring or water with food coloring will give them that color first until fully absorbed, which doesn't affect them.
