Jelly Marbles Test Tube By Steve Spangler Science

Place these tiny, solid beads in water and in just a short time, you will have Jelly Marbles that have absorbed over 150 times their weight in water. These tiny spheres can teach big lessons in color mixing, light refraction and the important role hydrogels can play in maintaining a healthy environment. The possibilities for experimentation are endless once you drop these spheres in water. Conduct experiments to see how quickly evaporation occurs in different environments. The tiny spheres take up less space when dry, which is great for storage - but they can be re-hydrated again and again. Includes 1.16 oz. of clear polymer orbs, plus instructions for 3 experiments. For ages 6 and up.
