It is a common belief that on the day of the equinox an egg will balance.
To test this theory middle-school students at Colegio Menor San Francisco de Quito, a K-12 school in Quito Ecuador, spent the 2005 equinox day (22 September) making hundreds of attempts to balance an egg. Using both raw and hardboiled eggs we noticed that at various times an egg would balance. However it was quickly realized that this was due to either placing the egg on a rough textured surface like the asphalt on the playground, or it was due to repeated use of an egg which eventually led to the ends of the egg becoming cracked or flattened.
This picture to the right, and the one below were taken at approximately mid-day.
However, a student was able to repeatedly balance an egg on a smooth marble surface. What did he do? Click here to see a short video of this balancing egg.
