The Time-Travel Box

A collection of science-inspired tools and collectibles that explore the concept of the fourth dimension. Each item demonstrates physical principles or celebrates time travel concepts from popular culture.

Inside Your Time-Travel Box:

4-Dimensional Tape Measure – The first tape measure that measures both space and time. This cleverly disguised pendulum demonstrates the relationship between distance and duration.

Goofy Giggle-Jiggle Siphon Straws – Two self-starting siphons that move liquid from one container to another with a quick jiggle. They demonstrate fluid dynamics and can also be used as regular straws.

Inq's Practical Slap Bracelets (Set of 3) – Three functional slap bracelets: one works as a ruler, another measures cylinder diameters, and the third contains "proof from the future" for time travelers.

Types of Time Travel T-Shirt – Features major time travel theories from movies, books, TV shows, and other fiction – from popular classics to obscure references.

Animal Architecture Coffee Table Book – A full-color book exploring how animals design and build their structures, from termite mounds to beaver dams.

The Box Itself – Features an anamorphic-letter tribute to Einsteinian relativity with the words "spacetime" and "massenergy."
