Making Better Magnetic / Ferrous Silly putty, with Lube!

I know the title is a little bit provocative, but stay with me here.

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!

Mostly the same as other Instructable.
  • fine ferric iron oxide powder (the pigment powder can be ordered online, or in some art shops)
  • Silly/color/thinking putty
  • gloves
  • 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)

Yo, could I do this with this:

http://www.lotioncrafter.com/dm350-dimethicone.htm...

cause it seems to have dimethicone too.

I'm so glad to find this.

It seems the Internet is awash in "silly putty" that is really "slime" a substance with completely different characteristics and ingredients quite often.

Finally I figured out what I needed to do to soften up some silly putty I bought for the same reason you did, when on a search your article came up.

I'm glad to see you went to all the trouble for me!

Thanks!

As an aside, I figure the only thing that kept magnetic silly putty from becoming a fad is the price. It's prohibitive for something that is so small and requires someone to just enjoy the innate characteristics of the stuff.

I read this with much amusement. 'Gun Oil'. LOL! Your instincts were correct but the source is questionable. First off, it is not pure silicone oil (polydimethylsiloxane), and second, it is probably expensive because of its 'underground' nature. :) You can get pure silicone oil on eBay for like $4-5 (including shipping) for 2 fl. oz. That's enough for a lot of putty. Search for "silicone shock oil." You can also get it at R/C hobby shops. I bought some on eBay and worked several cc of it into my homemade magnetic putty with dramatic results. It went from stiff and dry-feeling to soft, smooth, and supple. The 'magnet-swallowing' demonstration went from almost 3 minutes to just 32.5 seconds! No fast-forwarding necessary. ;-) I made a video, showing a side-by-side comparison.

All those 'cones are types of silicone...I wonder if the types they use in make-up primers--like dimethicone--would work?

Killbox, the mad genius! It never would have occurred to me to use lube, and I can't wait to try this.
check your weights on the putty... 13oz? looks to me like you're using the eggs that are about 1/2oz? certainly not 13.

oops, 13g (0.46oz). good catch. Thanks *edited now*

Wow, nice work!!
If you have some of the original and the upgraded version a side-by-side video comparison would be awesome!

Don't be embarrassed about the supplier. I find that when it comes to non-petroleum based/nylon safe lubricants the sexshop is the only place that sell high quality stuff.

Does the putty still bounce?

killbox (author)  dombeef3 years ago
yes, also if quickly jerked apart it shows its non-newtonian roots by breaking. although sometimes it just strings out!

feels a little more sticky, but i think thats just it getting down into the grooves of your fingers faster kinda like how geckos climb glass.

it still pulls off of the magnets and out of a container like normal putty , but if you hold up a blob between 2 fingers you can watch it stretch and drip.
