I found the fantastic Instructable on "Magnetic Sillty Putty" And just had to give it a try, It took me a bit of work to find the right mix, due to the dollar store sized lumps of "color putty " being different sized. but eventually i was able to make a product just like the other Instructable noted. and it was fantastic.
Although it was a bit stiff/slow. I kept wondering if it was possible to thin the putty down somehow.
Indeed you can, and this Instructable will say how, and show a little bit of how it differs.
Skip to step3 if you already have magnetic silly putty, or already have seen the fine Instructible listed above!
Step 1: Materials,
- fine ferric iron oxide powder (the pigment powder can be ordered online, or in some art shops)
- Silly/color/thinking putty
- some waxpaper or disposable surface to work on,
- Silicone based personal lubricant.* This is a scent free, lubricant, that claims to be medical grade.
*The one I used has the following ingredients.
Cyclopentasiloxane, Dimethicone, Tocopheryl Acetate(Vitamin E), Aloe. (Not sure if they are all needed, i suspect the desired effect is in one of the first two)
