“ADD HOT LIQUID WATCH A HIDDEN MESSAGE APPEAR… COLOUR CHANGES TO VARY DESIGNED MOTIFS. CONCEAL OR REVEAL ON THE SURFACE.”

What Allee has to say about this:
I’ve seen these where the clothes disappear when hot liquid is added but never where hidden messages appear. Have you used this and, if so, what are the messages? I can only imagine… And what on earth does “COLOUR CHANGES TO VARY DESIGNED MOTIFS” mean? Not that I understand “CONCEAL OR REVEAL ON THE SURFACE.” either.

Love the speedo.
