Step 5: Experiment and have fun!

Picture of experiment and have fun!
That's it, you're done! Grab your magnet and start experimenting with your new magnetic putty.

You can stretch out a strand and make it follow your magnet, you can polarize your putty to work as a magnet itself, and then there's the classic of placing the magnet directly on the putty and watching it envelop the magnet. There's plenty of fun to be had, check out the video I made with some of the fun you can do.

Some frames have been sped-up to illustrate magnetic properties.
Of course, aside from being magnetic your putty still retains all the properties of the original Silly Putty.

Putty has been known to leave a residue on some surfaces, even more so with the iron oxide powder. Use caution when playing with your magnetic putty.
If you get magnetic putty stuck to fabric you can try placing the magnet on top of the fabric and the putty may work it's way out (wait 24 hours). Alternatively you can apply rubbing alcohol to area and work out the putty, try a concealed test-area first. WD-40 may also work. If all else fails, take the fabric to the dry cleaners and tell them it's a silicone-based stain.

What are you waiting for? Get going and make your own magnetic putty!

I'm gonna mix it with some oobleck and see what happens.

But if silly putty is a silicone based substance wouldnt hitting it with high voltage heat it up and possibly turn it into a glass like substance?
haha my little bro made silly putty in his class, may borrow it for experimentaion......

Nope, it might if the silicone was actually silicon ...

I didn´t read the 432 comments, so I have to ask you if someone else talked about it. You can make your own black iron oxide using very simple things: steel wool, vinegar, hydrogen peroxide and household ammonia. I am a chemist and I can write an instructable for this (if nobody did it already). Unfortunately it is hard to find silicone putty here in Brazil... I will have to try this with white glue slime instead.
totally cool!

I wasted $17 today to learn that not any black pigment will work. I even brought the magnet into the art store and tested the pigment which was definitely magnetic, but when mixed with the putty it wasn't anywhere near strong enough to even phase the magnets. The magnets I used are insane too - they have an attraction field of about 3-4". And I can't find Schmincke pigments anywhere locally. I guess I get to go back and find some pigments with serious magnetic attraction. The other huge difference I noticed in mine versus the one shown was that mine was very dry and very hard - the putty shown looks almost like a liquid. I have no clue what I'm doing wrong, but I'm going to blame it on the pigment I bought and try again.

I did learn that ferric pigments are only in the earth-tone range, though - black, brown, yellow, red, and orange. So no blue, green or violet.

"mine was very dry and very hard - the putty shown looks almost like a liquid"
The viscosity of the putty used will definitely effect the results with your magnetic putty. Your putty should look 'wet' without any pigment added. If your pigment powder was magnetic when you placed a magnet next to it in the store it should work in this application.

Also, while black, brown and red pigments are ferromagnetic some blends of other colours (cobalt blue) may also be magnetic. But, they'll mostly be earthy tones that use iron derivative (Fe) as the main blending ingredient.

Funny I thought I read that I should wear gloves, but in the photos the guy doesn't have gloves and in fact has very dirty fingers.

Are you still offering the 3 month membership? I made it with red iron oxide and it works!
that is so cool

How do you polarize the putty?
the magnet is the only polarized thing in this experiment
you dont

Love their stuff. I also love this putty!

Love the stretch.
The video reminded me of Spiderman 3 :D

Very interesting. Has anyone tried this magnetic silly putty in a coilgun?

I have a recipe for making silly putty so I'm going to experiment with doing it for scratch. Plus this gives me great ideas for making all my non-newtonian recipies magnetic! (magnetic gak, moon sand, etc... :D)
Arc413 jnaude14 years ago
What is the recipe? I've just had a quick hunt, and couldn't find any.

Care to share? :)

YES, YES it is... (insert evil scientist laugh!)

Please someone post the recipe for the homemade silly putty!! :)

I'm interested in learning more about making the putty into a magnet. could you tell me how I go about polarizing the ferric iron?

Any rule of thumb for how much powder the putty will take up? I'm thinking of adding some graphite to try including conductivity in the putty's behavior.
mikeasaurus (author)  Guytron4 years ago
Surprisingly, the putty absorbed all the powder I added with no loss of consistency. I imagine you could add double what I show with minimal performance issues.

A mix of graphite sounds promising, you must share your results!
