Brodi's egg experiment-Patricia and Brodi


Wow, look at what fun experiment Brodi has discovered.
Over the weekend. Brodi did research on soft shelled eggs
and she found this.  Eggs contain something called calcium
carbonate, this is what makes eggs hard. Vinegar is an acid
known acetic acid. When the egg and vinegar combine, a chemical
reaction takes place. A carbon dioxide gas is released. Brodi discovered
off Jonte's egg experiment.
So that night Brodi went home and tried to do the experiment.
All you need to do is get a container and get white vinegar and an egg. Put the egg in your container with the vinegar covering the whole egg and then you wait three days. Then your egg will be like a cooked egg and the shell will fade away completely.  Amazing!
