You know when you're setting at your desk bored and just playing around with a paperclip or any gizmo around you? Well, we just found the one to rule them all: the Ferrofluid Magnetic Display. Using the magnets, control the ferrofluid inside the bottle and get amazed by its behavior as you create spikes and other cool shapes. You might go 'meh, nothing special', but trust me, it is one addictive gadget you won't let go.

Here are the links to Concept Zero's online stores where you will find other shapes of ferrofluid magnetic display bottles.
