Materials Coke Sprite7 bowls with lids Vinegar E2 juice Powerade Orange juice 7 eggs Water
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.
Aim:We want to find out which liquid can make an egg go squishy and bouncy the fastest.
Our hypothesisWe think that the vinegar will dissolve the shellbecause the acid in the vinegar will melt the egg shell and make it rubbery.
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.
Conclusion:Our hypothesis was right because we guessed that the vinegar would win because it is made of acid.
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 anegg 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.
Heres what happened: Several things happened to the eggshell while it was soaking inthe vinegar. The vinegar is an acid and it caused the shell materialto breakdown into two different materials. One is carbon dioxidebubbles 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 limestonecaves. 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 theshell* leaving the flexible membrane. The egg might bounce but will more likely simply splatter.
