Astronomical Toilet Paper


Go ahead, make the joke you’re dying to crack in the comments.

The Astronomical Toilet Paper (ATP) is a novel tool for popularization of astronomy.

When you look up to the sky, you can feel the expansiveness of the universe. Astronomy is a backyard matter in itself. This close relation, however, sometimes makes you be oblivious to the fascinating aspect of astronomy. With the ATP, we can bring fruits of astronomy in dairy scenes of the public.

The ATP is the first product of the TENPLA Project, a community of students, astronomers, and staffs of science museums and planetariums in Japan for popularization of astronomy.

    They both scour Uranus for Klingons.
