Ok, enough science. I'm sure we've all played with Thinking Putty in our youth, but how about magnetic silly putty?
By adding a ferrous component to an already wacky toy we can keep all characteristics of the original putty, but now have the additional dimension of magnetism! I've seen magnetic thinking putty for sale on other websites, but I'll show you how you can make your own for a fraction of the price and in about 20 minutes.
Enough talk, let's make some magnetic putty!
Step 1: Tools + materials
The secret ingredient that makes the putty magnetic is an iron oxide powder, which is ferric (magnetic). Ferric iron oxide is a fine powder used as black pigment and can be found at art stores. If your local artist supply store doesn't carry it, you can always purchase it black iron oxide powderonline.
