Egg and coke writing

Have you ever wondered what would happen if you put a boiled egg in a cup of coke?

Egg and coke

We did an experiment with coke and a boiled egg to see what would happen would it grow? would it dissolve? or would it just be the same? Our main observation we were looking at was the cause and effect on a boiled egg. I wondered for a second what if the coke bites through the egg and dissolves inside? Because of the carbon dioxide it might actually disappear but i think it might grow bigger than it’s normal size. My group thought of some ideas on what would happen and we all said it might grow or change colour.

How did we do it?

When we brushed the egg and it went back to its original our teacher said it was the citric acid and phosphoric acid in coke that erodes your teeth and made the egg change colour so i suggest after having a drink of coke or coke zero you brush your teeth and keep them clean
