Activity link broken? See if it's at the internet archive
This is an activity about acid-base reactions using eggs and vinegar. Learners place eggs inside a container of vinegar and leave to soak overnight. The calcium carbonate of the shell reacts with the acetic acid in the vinegar to make carbon dioxide, which is visible as bubbles. The end result is a shell-less, translucent egg that is ready to be used in experiments with different solutions (such as the separate activity, "Experimenting with Naked Eggs!").
