Riya, What you are appear to be doing is called "dry labing an experiment" in which you don't do the experiment but you fill in all the blanks and write a report as if you did. This is a no-no in science. Experiments are done to confirm a theory or to see what will happen if ...

science experiment (bouncing egg)
From what I've read, (I've not performed an experiment on one), coke contains acids (citric, phosphoric, carbonic, etc) and these dissolve an egg shell just as vinegar does. So coke can make an egg bounce. You may want to post the details of your experiment.
