Invisible Ink Putty 4" Tin with Glow Charger (Ghostwriters)
Often used to encode top-secret information, invisible ink has a long and interesting history dating back to 4th century BC. There are all kinds of ways to make and read invisible ink (like heat and lemon juice), but our Invisible Ink Thinking Putty® uses ultraviolet light to mimic blue ink on a sheet of green paper. Write with the Glow Charger® and watch with wonder as your words evaporate into thin air.
This item is classic Crazy Aaron’s Thinking Putty, with a twist. Ghostwriters Putty allows you to draw and write directly on the putty with the glow charger that is included. Just point the light from the glow charger at the putty to make the color change, inscribe whatever you’d like, and watch your work soon disappear before your very eyes! This glow in the dark putty comes in 4” tins, is sold in three different colors, and is a great addition to the already popular Crazy Aaron’s Thinking Putty series.
Glow in the Dark putties may be pale in daylight but become vibrantly hued in dim light! Colorful Glow in the Dark putties glow with different lighting effects in dim light. All Glow in the Dark putties can act as a canvas for a Glow Charger (included with some types of Glow putty). Draw designs that appear in a different color and then slowly fade away! Glow Charger (#000796) is also sold separately.
Stretchy, bendy, breakable yet malleable Putty is so simple, so diverse, and so much fun to handle. But theres a whole lot more to putty these days! Enter Crazy Aarons Putty. Step aside, pink putty, and get ready for these wild deviations including metallics, glow-in-the-darks, magnetics, neon and more. But beyond their cool colors, the putty is great for keeping fidgety hands busy during school time and is also useful for building hand strength. Large tins have 1/5 lb of putty while Medium tins have 1/10 lb and Minis have 1/34 lb.
