The magnet between the bismuth crystals really is floating there freely, touching nothing but air, and it will stay that way until you disturb it. This is the perfect science gift, especially for those enthralled with physics or chemistry.
This pyramid is solid bismuth, and achieves perfect balance with this amazing metal's force.
How? Bismuth is diamagnetic, repelling both of the magnet's poles' (North and South) equally. The base supports a special array of magnets. This creates a magnetic field that works with the bismuth's diamagnetism to hold the little magnet in a small pocket of stability.
Combined base and crystals measures 4"x12"x2".
What you get: 1. A pyramid crystal that is shown in the photos 2. A magnetic array on the ceramic platform 3. For floating - Four 3 mm cube magnets - One 3 mm sphere magnet Extra and replacement magnets are always available.

It's very easy to set up. Just put the piece on a level surface. Slip your magnet in the pyramid slot. Then slide the crystal to either side until you achieve balance.
**Neodymium magnets are not for children. Small magnets can pose a choking hazard. If multiple magnets are swallowed, they can attach to one another through intestine walls. This can cause a severe health risk, requiring immediate, emergency surgery if correctly diagnosed.
**Neodymium magnets can affect pacemakers. The strong magnetic fields near a neodymium magnet can affect pacemakers, ICDs and other implanted medical devices. Many of these devices are made with a feature that deactivates it with a magnetic field. Therefore, care must be taken to avoid inadvertently deactivating such devices.
