Review on UWANTME Rainbow Growing Tactile Decoration by Ruben Saunders

Maximum size of balls in saturated state is only 9.5mm - 10mm. I was hoping for 20mm. Spring. The attached photos show the result of applying 1 tablespoon of desiccant before and after. As shown, 1 tablespoon fills a medium colander almost to the brim. For those who love the math, I measured the dry and wet diameters with digital calipers. Each of these dry spheres is 1.9mm in diameter for dry volume = 3.59mm^3 Fully saturated each sphere is 10mm in diameter for wet volume = 523mm^3 So the expansion factor is about 146x. The size of a container of these dry pellets is approximately 35mm x 107mm x 76mm or approximately 285ml / 0.0752 gallons. Volume. Using an expansion factor of 146x, the entire bead container will fill a volume of approximately 41.6 liters or 11 gallons at saturation. The average tub is about 80 gallons. You need about 7.5 containers of this substance to fill a medium-sized bathtub. It's better to do 10 just to be sure.
