After (mostly) cleaning the ferrofluid off of my magnets, I carefully removed half of the magnets and a washer, replacing them with a bit of Sculpey that weighted exactly the same. I pushed half of the magnets into the Sculpey, and then used them to hold another 17 magnets &#8220;outside&#8221; of the main body. This spacing keeps them far enough apart that they do not repel each other, and the Sculpey fills in the areas between the magnets.<\/p>\n<p>The Sculpey will probably lose some weight when it is baked, but I&#8217;m counting on the ferrofluid to allow me to adjust the weight of the hanging object suitably. I don&#8217;t want to test it with ferrofluid until after I bake the Sculpey and coat it with black spray paint. The punk potato has a magnet with a plastic cap on it, so I needed to determine the lowest possible temperature that will harden the Sculpey without demagnetizing the magnet or melting the plastic cap. (Currently, the &#8220;punk potato&#8221; is right at the lower weight limit for successful levitation.) As the lowest curie temperature I could find for common rare-earth magnets was 310 &deg;C, the plastic (which I assume is ABS, with a melting point of 105 &deg;C, (or 220 &deg;F) is my limiting factor. I set the oven to 215 &deg;F and wrapped some tinfoil around the plastic in an attempt to protect it.<\/p>\n<p>When I showed it to my wife she closed one eye, tilted her head, and said &#8220;Weird&#8221;, so I know I&#8217;m getting close to the aesthetic I&#8217;m aiming for. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The main problem I had with my previous ferrofluid test was that the magnets would repel each other enough that I was not able to achieve a single, solid object.
