HISTORY OF EARTH HELICAL JIGSAW PUZZLE
The world’s first helical jigsaw puzzle lets you trace the evolution of life on Earth as you build—a 535-piece spiral with a functional core.
SLIDE RULE CHOPSTICKS
A pair of stainless steel chopsticks that double as slide rules—perfectly ergonomic, unapologetically nerdy. 240mm long and 6mm in diameter, these chopsticks are more than just sleek. They’re smart.
BEZOLD-STROOP SHIRT
A wearable illusion combo of the Bezold and Stroop effects—this shirt tricks your brain in two very different ways. CIA-approved (maybe).
PUZZLE ME TWICE BOOK
A book of brain-busting puzzles by Alex Bellos—plus an exclusive Q&A with Michael Stevens, only in the Curiosity Box.
PRISM
A high-quality optical and geometric prism that splits sunlight into a stunning rainbow spectrum—made from K9 borosilicate glass for clarity and precision.
THE BOX EFFECT
Not a printing error! View the chameleon on the box through the proper angled prism, and the power of refraction makes the multiple images come together into one colorful creature!
