What came first... the chicken or the EGG??

Our science experiment today was EGGseptional, EGGsiting, EGGselent!!

We studied how steam engines work (for Mike Mulligan and His Steam Shovel AND for our trip this week to Greenfield Village when we get to ride a steam train!!)

We took an old glass milk jar and placed it in a pan with water.  We boiled the water and the jar.  Filling the jar 1/2 full with the boiling water we CAREFULLY placed it on a hot pad.  Dollar placed a peeled, hard boiled egg on top.  A few minutes later the egg dropped into the jar!!  When the steam evaporated, it created a negative pressure in the jar thus sucking the egg through the opening!  Way cool!
