Ferrofluid has been submersed in sugar water. Sugar has been added to increase the density of the water to the point where the ferrofluid appears weightless A ferrofluid (portmanteau of ferromagnetic and fluid) is a liquid which becomes strongly magnetized in the presence of a magnetic field. Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). Each tiny particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields. The magnetic attraction of nanoparticles is weak enough that the surfactant's Van der Waals force is sufficient to prevent magnetic clumping or agglomeration.

This floating black ball is the creepiest thing you'll see all day. Top 10 Mad Science-Worthy Chemistry Experiments. Chemistry is a fascinating science, but it's often taught poorly in today's boring schools. Here's how chemistry should be taught: by mad scientists! Here's Neatorama's list of the Top 10 Mad Science-Worthy Chemistry Experiments: 1. Briggs-Rauscher Reaction [YouTube Clip] The Briggs-Rauscher reaction is a well known example of oscillating chemical reactions, also known as chemical clocks because the periodicity can be used to tell time.
What's going on in the beaker is actually quite a complex set of chemical reactions. 2. Who'da thunk that Gummy Bear can be so ... violent? [YouTube Clip] 3. Mentos in various carbonated liquids. You've all seen this before. MythBusters explain: Whatever you do, don't eat a mentos then chug a mouthful of diet soda, mmkay? 4. [YouTube Clip] Yes, even elephants need to maintain good dental hygiene, but what kind of toothpaste do they use?
This one's easy to do, all you need is dish soap, hydrogen peroxide, and potassium iodide: Link 5. [YouTube Clip] Got that? 6. The most common phobia you've never heard of.
