Science Fair - Feb 6th

Ella did a neat science project on the effects of an egg shell when it is exposed to vinegar.  She covered each of the shells in toothpaste first, all with different percentages of fluoride.  It was neat to see that the toothpaste with the most fluoride kept the egg shell the hardest.  The control egg with out any toothpaste was really mushy and the whole shell pretty much deteriorated.  Way to go Ella!
