Just add water and watch these little clear and colored beads grow into giant jelly marbles. Before soaking, sort the different colors and ask science questions like “How are these alike, and how are they different?” Will the different colors grow to different sizes? Try it and see! Afterward, kids can have lots of fun playing with their experiments. Find a water-safe surface and play the slimiest game of marbles in town, or try them out as new jelly bouncy ball. Kids can even try to grow the amazing spheres in different liquids, like milk, vegetable oil, or salt water. Use a notebook and record hypotheses and observations.
