Ferrofluid Magician is a passion project that founder of Mr. Sci science factory Kevin Lin. And now they've gone to Kickstarter to attempt to raise funds to produce this educational toy. Ferrofluid is a magnetic liquid that becomes strongly magnetized in the presence of a magnetic field. They've placed a magnet in the top of the magician's hat (and a little pigeon is hidden underneath it).
You can pick one up beginning at the $29.00 funding level. Of course, they have several other funding levels, where you can pick up a number of various rewards.
This project will be funded on Wednesday, November 9th 2016 at 7:24AM EDT.
Remember...this is not a pre-order. There are many instances of crowd funded projects that have been funded never making good on their promised goods. So back with caution.
