It's An Eggsperiment!

In Science we've been talking about osmosis and diffusion.  The kids loved this experiment.  We first put our farm fresh egg in a vinegar bath overnight and by the morning the shell was pretty much gone. 

We then took our egg and placed it in a bowl full of dyed blue water for three hours.  And what a brilliant blue it became!  And finally we put it in a bowl full of clear water.  It was interesting to note how semipermeable the membrane of the egg is and just how blue most of the white of the egg became.
The dark blue blob at the back of the bowl is the membrane from the egg.
