So, Grandpa Bruce had this favorite mug that he got from work, sometime in the 1960s when he was selling primitive computers to nuclear scientists.

It's covered, all around, with a dense list of nuclear physics equations and constants. Not particularly useful at 7am when we can barely get the coffee machine to work, but interesting nonetheless.

Now that Bruce is no longer with us, we wanted to honor his memory by making a version of his mug that's genuinely useful to folks in the modern world. The Handy Mug is our attempt.

Handy Mugs are quite large -- "Fifteen Ounces so we can fit more facts."

Buy one to make a statement about yourself, or buy several as gifts--they suit almost every occasion from Birthdays to Christmas, Graduation to new parenthood.

And check back often -- we'll keep producing new variants regularly, for as long as people want them.
