Egg Science Activities

Step 1

Place an egg in the jar and cover with vinegar.

Step 2

Add food coloring if desired.

Step 3

Wait and watch! Notice the bubbles on the eggshell! This is the acid in the vinegar reacting with the calcium carbonate in the shell. This reaction is producing a gas called carbon dioxide!

Step 4

After 48 hours, carefully drain the vinegar and remove the egg.

Step 5

Rinse the egg carefully under running water.
