"Do not yield to discouragement in the face of difficulties and do not abandon yourselves to false solutions which often seem the easiest way to overcome problems. Do not be afraid to make a commitment, to face hard work and sacrifice, to choose the paths that demand fidelity and constancy, humility and dedication. Be confident in your youth and its profound desires for happiness, truth, beauty and genuine love! Live fully this time in your life so rich and so full of enthusiasm."
"Let us look with greater hope to the future; let us encourage one another on our journey."
~ Papa Benedict XVI

Chemistry is cool!

Yes, i was the one who avoided chemistry like the plague while in High School. Chemistry and Calculus - ugh! But now, well....it might have been fun....

B. was doing several experiments today and i decided to observe one (Cory usually does them with him.); boy did  I picked a good one!

It was showing the difference between chemical change and physical change. The physical change part was simple - place the beaker of water in the freezer.  Water changes to ice.  It expands. no big deal.  The chemical change part though - well....we'll just show you!


Safety!

the egg...

He placed the egg in the blue stuff.  As you can see, the calcium from the egg shell reacted with the chemical in the blue stuff ....

A bit of a time lapse...2 minutes....

Then he tried to retrieved the egg....
