Some Japanese students got a grant to promote astronomy–using toilet paper illustrated with star facts. After a successful launch in museums last year, the toilet paper is headed for public bathrooms.
Printed on the toilet paper is a description of the life of a star: the birth of a “star egg” with gas clouds in space, the nuclear fusion reaction starting its birth, the star’s expansion after its fuel hydrogen is burned up, and its death with the diffusion of planetary nebulae.
Available technology allows only repetitions of a 70-centimeter-long pattern, but the students say this is “just the right amount” because the process of the life of a star can be repeated in this length.
Far out, as we would have said in the Seventies. By several megaparsecs, very far out!
