 baking the eggs in the oven at 325 for 30 minutes. 

Hannah's Science fair is coming up and after googl-ing and pintrest searching we agreed on trying the Egg and Vinegar experiment. We are bringing you along for the ride, updating it everyday from our starting date: April 13th, 2012. I already know the answer, but for learning sake have not told Hannah. See the acids in vinegar will dissolve the white shell of an egg, leaving it transparent and rubber feeling. When you leave it out overnight it will try to rebuild itself.

An Eggcellcent Adventure

By Hannah and Family

Experiment: What will happen to raw and hard boiled eggs when left in vinegar and apple cider vinegar over night? for a few days? What happens when you leave it out?

Hannah's Hypothesis: I think the eggs will get fizzy. The next day they will explode!

Day one: April 13th, 2012. We took a hard boiled egg and raw egg

 and placed them both in vinegar and apple cider vinegar. What happened: They bubbled around the egg and are floating in the jars.

The 5th jar on the left is a cracked hard boiled egg we thought would be fun to put 50/50 water and vinegar with it.

Day two: April 14th 2012. The eggs in vinegar: hard boiled: rubbery, shell still there- more bubbles around rim  raw: rubbery and see through. The eggs in apple cider vinegar: rubbery, shell still there- more bubbles around rim   hard boiled:  raw: rubbery, shell still there- more bubbles around rim.

In the morning:

 Exactly 24 hours later: Notice the the far left jar compared to the rest? the shell is gone!

Vinegar soft boiled egg:

Day three: April 15th,  2012. The eggs in vinegar: hard boiled:  still rubbery,  raw:  transparent and slightly bigger than other eggs . The eggs in apple cider vinegar:   hard boiled:  still rubbery,  raw:  Now transparent and slightly bigger than other eggs .

We drained the water after feeling each one and will let them sit out over night.

Day four: April 16th 2012. The eggs in vinegar: hard boiled: still rubbery  raw:    When we felt this one, it broke!!  The eggs in apple cider vinegar:  hard boiled: rubbery  raw: too afraid to touch this one!
So since the full vinegar egg broke (second to the left), we added a new full vinegar raw egg (all the way to the right)

Day five: April 17th 2012. The eggs in vinegar: hard boiled: still rubbery  raw:    When we felt this one, it broke!!  The eggs in apple cider vinegar:  hard boiled: rubbery  raw: still too afraid to touch this one!
New Vinegar egg: almost fully transparent!

Conclusion: Hannah was close. They did fiz, however they only exploded because I touched it. I read that if you add them to water they are supposed to expand and burst- ours did not. They also did not start getting hard again after being taken out of vinegar

If you found this helpful or fun, please follow me, it gets a little lonely feeling like I'm talking to myself.
