Phil Plait and others have debunked the idea that you can balance an egg on end only on the vernal equinox. He then shows that a little patience can lead to egg balancing on any day. Wanna see patience?
A local artist, Justin Zaremski balances lots of things like rocks and tools. He makes some of the most amazing balancing sculptures. He just sent me a new one which I thought was pretty amazing.
I guarantee that this is not a photoshopped image, there is no glue involved, there are no tricks of any kind. Just patience and perseverance.
