What I noticed right away:
--- The egg
was covered in bubbles.
---
Nothing noticable.
--- Nothing noticable.
--- The egg floats.
--- Some bubbles in the soap,
but it was hard to tell because of the thickness of
the soap.
--- The bubbles on the top
remained for longer than normal, and never fully
disappeared.
--- Lots of bubbles, but nothing
amazing.
Results after 12 hours (experiment 1):
o--- Shell rough, shell
slightly worn away.
o--- No results.
o--- Egg rough, shell
slightly worn.
o--- Egg stained light
brown.
o--- No result.
o--- Egg very slightly
stained, took 2 drops to break it.
o--- Stained dark brown.
Results after 24 hours (experiment 2):
--- A definite change. Egg
was rounder, shell almost completely gone, squishy but firm. Still broke when dropped. Floating.
--- No result.
--- Egg rough, worn, slimy. Floating.
--- Stained brown. Floating.
--- No result.
--- Brown tint. Floating.
--- Very stained, but stain rubs off mostly.
Floating.
Conclusion: (Experiment 1) None of the eggs were bouncy at all. None of them
even had the shell worn away. Therefore, the experiment was not very successful. The book I got my idea from reccomended leaving
the egg for 24 hours and I only did 12. I may redo the experiment and do it for 24 hours instead. If I do I will add the results.
(See below.)
However, I did notice that the vinegar and orange juice both made the egg
rough. These substances are both acidic, which means that my hypothesis was correct, and acidic subtances wear away the egg
the most.
(Experiment 2) This time, there was a noticable difference to the egg in the vinegar. It did not
bounce, but the shell was mostly gone. The only other one with a real reaction was the one in Orange Juice. The rest were
either no result or stained, which doesn't mean anything because they were in brown liquid. So since the Orange Juice
and vinegar were the most acidic, my hypothesis was correct and the most acidic liquids work the best.
Discussion: I think that this experiment
was an interesting one to do. My hypothesis was correct as to what would happen, however it didn't happen on as big a scale
as I thought it would. The eggs, even the one in the vinegar, did not change as much as I thought they would. This was a fun
experiment but not one that was very useful overall. I did enjoy it, though. If I ever do the experiment again I might try
it for longer, maybe 36 or 48 hours.
Experiment 1 performed: February 20-21, 2008.
Experiment 2 performed: February 21-22, 2008.
