You know how, in that movie Arrival, the aliens communicated in a language through squirting ink into the air that coagulated into a circular mist, like a satanic snowflake? Well, you can get that same kind of language from your cup water! Take a sheet of paper and drip a little bit of the sweat pool onto a blank spot. Whenever, or if, it finishes drying, maybe you could say “Could you spare a light?” to an extraterrestrial being. (If you don’t have access to paper, you get 300 free prints at Addlestone Library – type the letter “A” onto a document on Microsoft Word and print that. No more, no less.). However, if you have trouble seeing your watermark, then maybe go see an eye doctor.
