Mossad Pen has visible, then invisible, then visible ink

The "Mossad Pen" from Shomer-Tec ($28) writes with what appears to regular, visible ink. Hit your scribblings with a hair dryer, however, and they'll disappear. Pop the blank pages in the freezer and they're back! It's exactly the sort of high-tech invisible ink that I'm sure the Israeli intelligence cadets are using to pass messages around in class right now. Can you believe we've done this site for nearly two years and we still don't have a "Spy" category? I think that says a lot about what gadgetry has become over the last couple of decades.

    looks like the other end would make for a decent weapon as well.

    What’s hilarious is the name “Shomer Tec.” Shomer is Hebrew for “watchman,” or something like that.

    …Jeez, is there some kosher problem with lemon juice that the Mossad can’t stick with the traditional method? Either way, I’m up for a spy tech theme for BBG. Especially if you can find someone who’s got all those classic Mattel Agent Zero-M toys to do a thread on!

    @3, I just rewatched Who Framed Roger Rabbit this weekend, that was my first thought as well.

    Duh. This is a Pilot Frixion erasable gel ink pen. Marketed as an erasable pen you can “erase” the ink using the high friction rubber end. Heating the ink causes it to fade out. Low temps bring back the color.

    Except these cost a couple of buck!
