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 polymer when you hide and then uncover your own secret message.  We’ll even throw in some regular marbles, so you can prove to any skeptics in your audience that Jelly Marbles are not your average marble!  Recommended for children ages 8 and up.

What's included?

• Plastic pie pan
• 10 grams of Jelly Marbles
• 7 Dram vile
• 3 Glass marbles

How does it work?

The message looks scrambled because the rays of light are scattered by the water-filled Jelly Marbles.  It’s like trying to look through broken glass.  When water is added to the dish, the light rays pass right through the water and the spheres without being scattered - due to the Jelly Marble's identical index of refraction with the water.
