Overview: You Won't Believe Your Eyes! These Jelly Marbles become invisible when submerged in water but grow almost 7 times their size! Just add water and discover the magic!
  • GET STARTED: Place these tiny, solid spheres in water, and in just a little while you will have your own squishy Jelly Marbles that absorbed over 150 times their weight in water. These superabsorbent water marbles are the newest craze around the Spangler Science offices! What starts out as a 3mm pebble quickly becomes an approximately 20mm ball of jelly!
  • STEM: These tiny spheres teach a big lesson in color mixing, light refraction, and the importance these thirsty pebbles can play in maintaining a healthy environment. Not only are these superabsorbent marbles fun, they teach a valuable lesson about the power of polymers. Jelly Marbles are an example of amazing hydrogels. Hyrdrogels are superabsorbant polymers that are saving the environment.
  • SHAPE AND COLOR: Watch Them Grow To the Shape of One of Our Baby Soda Bottles. Your young scientists will be surprised to see that the marbles maintain their spherical shape. Not only do these clear spheres absorb water, but they can also absorb color to make them even more interesting!
