Two Birds with One Stone...More or Less

I feel the need to be extremely resourceful with lab supplies that I use during class.  I try to get every last drop or every use out of EVERYTHING.  The latest lab was a lab that used eggs.  We melted the shells off with vinegar (this takes about 2 days), then we put one egg in water, one egg in corn syrup and one in vinegar again.  The point was to show how membranes are selectively permeable.  It results in the egg in water swelling, the egg in syrup shrinking, and the egg in vinegar staying mostly the same.

When you are done the eggs feel like water balloons.  Well, if something feels like a water balloon you HAVE to throw it...its like a rule or something.  We happened to be playing the school rivalry that evening and I just happened to have cardboard cutouts of their school's mascot posted up next to electric poles outside....

I thought my kids were going to laugh themselves silly throwing these shell-less eggs at these cutouts.  I thought I was too!  We had a ton of fun that day.  It's even going to make it into the yearbook, which I think is pretty cool.

So your are probably wondering if we won the football game that night.  I would love to say yes by a large margin, but we lost by a very large margin.   Oh well, you win some, you lose some.  But I got my double duty out of my eggs that day!
