The National Geographic Mega Science Series Glow-in-the-Dark Science Kit includes four amazing science activities that will ignite your imagination. This kit includes both purple and green glow-in-the-dark slime kits, allowing you to make your own slime right at home.

There's also an incredible glow-in-the-dark putty available, along with a UV light keychain that lets you draw glowing images or words into the putty itself.

You get everything you need to grow your own glow-in-the-dark crystal, along with a fluorescent wernerite sample that glows when you shine UV light on it.
The kit includes instructions for each activity, as well as a complete teaching guide that teaches everything about crystals, slime, putty, and fluorescence.
