Oddbean new post about login | logout Got this mug while touring space X This past summer. Changes color when hot liquid hits it. https://static.noagendasocial.com/media_attachments/files/111/183/308/582/456/521/original/f380069791840f90.jpeg https://static.noagendasocial.com/media_attachments/files/111/183/308/591/998/706/original/248b9a175763dee9.jpeg
@449841af For a while. I have two coffee cups from working B-2 and F-23 (not 22). Both were stealth aircraft and were only visible on the cups when filled with a hot drink. They are over 10yo now - both show the aircraft (and not the cloud) when cold.
