" scientists James S. Brooks and Jos A. A. J. Perenboom have conducted a series of experiments at about 20 Tesla; numerous biological and organic specimens were placed in the center bore of a magnet, and positioned in such a manner that the diamagnetic repulsion was compensated for by forces of gravity, allowing levitation of the specimens." Quicktime movies of the floating frog are here.
While I don't know if any floating frogs will be present, I do see that the The National High Magnetic Field Laboratory will hold its 11th Annual Open House on Saturday, February 18 2005, from 10:00 a.m. to 3:00 p.m in Tallahasee, Florida.
- Highlights include:
- Potato Canon -- demonstration that showcases projectile motion by shooting a potato into the lake behind the Magnet Lab.
- 900 MHz magnet – the laboratory's newest world record magnet that stands 16 ft. tall and weighs 30,000 lbs. Scientists use this magnet for chemical and biomedical research.
- New introductory video – repeat visitors will enjoy this new production that showcases the lab, its scientists, and their research.
