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.
Two included magnets double the fun
Ferrofluid in a Bottle (60mL size) includes two small neodymium magnets which allow for some uber 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.
Ferrofluid is the astonishing liquid that becomes highly magnetized in the presence of a magnetic field.Place any magnet close to the magnificent space putty and take note of the puttyÃ¢â‚¬â„¢s instant gravitation and shape shift. | You can make drops, pieces, spikes, and a little foot, by changing the moving speed, force, combination of the magnets. | You may also enjoy the fun and fascinating moments of playing and being imaginative which you definitely won't be able to resist. | You can even make it dance.Use your imagination and imaginative magic.Each glass bottle contains 2 ounces suspension solution . | NOTE: THE FERROFLUID CAN'T STAND LOW (BELOW 0 CELSIUS) AND HIGH TEMPERATURE (ABOVE 48 CELSIUS) OR IT WILL BE BROKEN EASILY. PLEASE TAKE A NOTE OF IT BEFORE PURCHASING.WE WON'T TAKE THIS RESPONSIBILITY IF YOU IGNORE IT.UPC
