Ferrofluid is the astonishing liquid that becomes highly magnetized in the presence of a magnetic field.
Comprised of nano-scale magnetic particles suspended in a transparent liquid, undisturbed ferrofluid forms into a smooth pool. But when a magnet is brought close, ferrofluid reacts in strange and fascinating ways.
With Ferrofluid in a Bottle, you can safely and easily play with this spectacular substance. Using the included neodymium magnet(s), you can spike, toss, drop, pull, and bridge the ferrofluid. You can even make it dance.
Ferrofluid is for fun / blowing your mind
A liquid magnet = hours of fun. You can spike it, toss it, drop it, stretch it, bridge it, and make it dance. It\’s basically a fidgeters dream come true.
Because ferrofluid can be messy and stains easily, the manufacturer smartly sealed it inside a bottle. Plus, its metal cap makes for a great place to store the included magnet when not in use. Simply put, Ferrofluid in a Bottle is the best way to experience the magic that is ferrofluid.
Those spikes are magnetic field lines!
Most of us have performed (or seen pictures of) the classic magnetic field experiment. You place a bar magnet underneath a piece of paper and then sprinkle iron filings on top. The filings arrange themselves in such a way as to approximate the magnetic flux lines.
Using Ferrofluid in a Bottle, you can see this phenomenon in real-time and in 3D! The stronger the magnet, the larger the spikes. And the closer the magnet is to the ferrofluid, the closer the spikes will be to each other.
Usage note: Leaving the magnet against the ferrofluid for extended periods of time can cause irreversible damage to your ferrofluid such as it no longer being able to spike. When not in use, keep the included magnet attached to the cap of the bottle or in a separate location.
Two included magnets double the fun
Ferrofluid in a Bottle (60mL size) includes two small neodymium magnets which allow for some über cool interactions. You can bridge the fluid across the walls of the bottle as well as create a yo-yoing effect by moving the magnets back and forth.
WARNING: Keep away from children. Do not put magnets in mouth or nose. Swallowed magnets can stick to intestines causing serious injury or death. Seek immediate medical attention if magnets are swallowed or inhaled.Don\’t break the glass. When you\’re done, you can store the magnets on the top of the bottle cap.
