2. Materials
Coke
Sprite
7 bowls with lids
Vinegar
E2 juice
Powerade
Orange juice
7 eggs
Water
3. Method
1.Get 7 of the same containers and place them on a bench in the same area.
2.In each container put 1 egg - this needs to be the same size and brand.
3.Pour the same amount of liquid in each. Measure this carefully as it needs to
be exact.1 with coke, 1 with vinegar etc.
4.Put lids on each container.
5.Wait for three weeks and watch the magic happen. Do not move or 'fiddle'
with as this might change the outcome.
4. Aim:
We want to find out which liquid can make an egg go squishy and bouncy the
fastest.
5. Our hypothesis
We think that the vinegar will dissolve the shell
because the acid in the vinegar will melt the egg
shell and make it rubbery.
6. Results:
The vinegar has won but Hugh popped it. The vinegar had made all the
calcium come off the shell.
The orange juice came second but it did the same as the vinegar but it took
longer.
The e2 juice came third because it made the shell squishy but not that fast.
The coke came fourth because the shell broke when Hugh picked it up
because it was a bit rubbery.
The powerade came fifth because he made the shell red and all rocky.
The sprite came sixth because it made the shell brown.
The water came last because it did nothing.
8. Discussion/reflection:
We found out that the coke takes exactly one year to make it rubbery. The
vinegar only did it in two weeks. We found out that the vinegar can make an
egg shell go rubbery and so does the orange juice. Next time if we did it again
we would leave the vinegar in there longer and see if it would completely
vanish the egg.
9. Here's what happened:
Several things happened to the eggshell while it was soaking in
the vinegar. The vinegar is an acid and it caused the shell material
to breakdown into two different materials. One is carbon dioxide
bubbles that were released into the air. The other material is lime.
The lime remains in the solution. Also, the appearance of the
shell changes the result of this chemical reaction. This is a fairly
common process. It happens in nature a lot, creating limestone
caves. This chemical reaction also attacks your teeth. Yuck! Makes
you want to go brush your teeth!
Soaking an egg in vinegar dissolves the calcium carbonate in the
shell* leaving the flexible membrane. The egg might bounce but
will more likely simply splatter.
