THE USEFUL T-SHIRT

This incredible wearable reference includes all the information you’re likely to need, and the precision you require! For example, you’ve got pi to 38 decimal places; using that many digits allows you construct a circle with the circumference of the known universe, to the width of a hydrogen atom. It is only available inside the fall Curiosity Box along with 8 other curiosities designed to feed your brain! 

THE FALL 2020 BOX INCLUDES... 

The Useful T-Shirt
A Build-It-Yourself Remote Controlled Car Kit
