Water on the Moon!
Avast! There be water on the moon. Now the return address I practiced writing as a kid:
Edith P. Giblets, 1234 Hammington Road, Gaia’s Crater, Diana District, The Moon
may finally be used. Except that back when I imagined that, there was no Internet and now people don’t write letters. But still. Water on the moon! Let’s go!
