Product Description

Call them what you want – water marbles, water beads, clear spheres or jelly marbles – your audience won’t believe their eyes when you “magically” uncover a secret message with this Jelly Marble polymer demonstration kit. Just add water and watch these tiny spheres turn into big jelly-like marbles. Then teach a captivating lesson about light and polymers when you hide and then uncover your own secret message. You can prove to any skeptics in your audience that Jelly Marbles are not your average marble!

It looks like an ordinary glass of water… crystal clear water. But hiding just below the surface of the water are an amazing collection of large, jelly-like marbles that become invisible when submerged in water. The Jelly Marbles become invisible due to an identical index of refraction with the water. In other words, they vanish like magic! As you’ll see, there’s more to this experiment than meets the eye.

The Vanishing Jelly Marbles Kit is also a great object lesson. Don’t just tell your students that the Jelly Marbles will disappear and why, give them some science fun. Are you teaching your lesson in March? Perfect! The Vanishing Jelly Marbles are magical Leprechaun eggs. If your lesson is in the fall around Halloween, these Jelly Marbles are perfect ghost droppings or eggs. The possibilities are as limitless as the human mind.
