I actually thought the magnetically levitated frog was pretty cool and the Ig Nobel award undeserved. Now his credibility is clearly vindicated as graphene would be the most important substance to have been discovered since metal.
My impession is the Ig Nobel is recognition for research that seemed pointless.
ig·no·ble/igˈnōbəl/Adjective
1. Not honorable in character or purpose.
Levitating a frog is a classic demonstration of diamagnetism. Most materials, including living things, actually repel magnetic fields. A strong enough field can cause a repulsion force stronger than gravity.
Comparing Hell and a Black Hole deserves to win the Ig Nobel.
