You may be familiar with thermochromatic and light-sensitive inks that change color based on changes in temperature or light. Coors beer cans, "mood" rings, and color-changing nail polish are examples.
What I am looking for is a way to (invisibly) treat paper so that the ink from a single pen will look different depending on whether the ink is used on untreated paper or treated paper. For example, writing on the untreated paper, the ink will appear blue, while writing on the treated paper (with the same pen) the ink will appear red. I have several uses for this that I would be happy to share if someone could point me in the right direction. There used to be (or still are) markers that write in one color, but when wiped with a clear substance, the ink would change color. In essence, I'm looking for a pen that will write in two different colors without having to fiddle with the pen. Thanks, DK |

You know the magic markers for kids, with the clear marker that changes the colour of the ink when you draw over it? Pre-treat the piece you need with the clear pen.. They come in a pack, they are marketed for kids.

Pturtle,
I mentioned those markers in my original post, but don't know if pre-treating the paper with the clear marker would effect the change. Do you (or anyone else) know? Thanks, DK P.S. On a related theme, it would be nice to have paper or cardboard that could quickly change color (for example, from blue to red). Perhaps it could change upon touching something (like a warm pad or plate) in a pocket or hidden under a mat or in a book. Both permanent and temporary changes would be useful for a wide variety of applications. |

Does anyone know where one can pick these up in the uk?
I want to perform the routine from mitox, but as of yet, havent been able to find ANY. I used to have them as a kid, well a teenager at least, and I'm sure they were everywhere, now I cant find them! Any help would be mucho appreciated. I might even say thankyou! Jon Hackett

Looch,
No, I haven't been tipped off, but I have worked on such things in the past. My Frixion marker, my heated socks, my "hot plate special" close-up mat, and my "Hot Pad" (writing pad) are all components and devices I've played around with. I did produce a viable "X Marks the Spot" using these methods, but that's another story. To All, As previously mentioned, I am currently looking for "a way to (invisibly) treat paper so that the ink from a single pen will look different depending on whether the ink is used on untreated paper or treated paper. For example, writing on the untreated paper, the ink will appear blue, while writing on the treated paper (with the same pen) the ink will appear red." As I wrote in my original post, "There used to be (or still are) markers that write in one color, but when wiped with a clear substance, the ink would change color." Psychicturtle assures us that "pre-treating the paper with the clear marker would effect the change." However, it would be nice to have a fine line marker (best would be a pen or even a pencil) that would produce a different color on the pre-treated paper. Does such a thing exist? As I also wrote, "[I]t would be nice to have paper or cardboard that could quickly change color (for example, from blue to red). Perhaps it could change upon touching something (like a warm pad or plate) in a pocket or hidden under a mat or in a book. Both permanent and temporary changes would be useful for a wide variety of applications." I'm glad to hear that there's some "underground project" somewhere working on a similar idea, but that doesn't do me much good. Does anyone have any information that could help me solve the above problems? Thanks to all! DK |
