What’s a Curiosity Box?
We’re the Inq Factory team, led by Michael Stevens of Vsauce. Every season, we pack a box with things we invented, wrote or designed, so science becomes something you can pick up and play with. Schools and homeschool families use it for hands-on learning that teens actually want to open.
Brand-new inventions
Subscribers fund strange, ambitious builds that start in our workshop, like a ruler that measures in any unit.
Real science, not crafts
Each item is built around a real principle: optics, logarithms, symmetry, atomic structure.
Limited editions
Made in small runs for subscribers first. These items never reach retail stores.
Straight from Vsauce
Most ideas come from Michael himself, and every item gets his stamp of approval.

What families say
I used the packages for my homeschooled son; they’re the best. High-quality and interesting topics. Easy to use but complex enough to tickle the curiosity of my teenager.
My son wanted the Curiosity Box as a birthday present and we ended up doing it for two years. Lots of little gadgets that were fun and teachable, easy to work into learning activities.
The Curiosity Box always arrives beautifully intact and is so full of high-quality, educational, fun things. It always sparks curiosity in our kids!
