Materials Needed
distilled vinegar (approx. 24 oz), 3
clear glass cups, 3 eggs

water (approx. 12 oz), red food dye,
alcohol, labels for cups, recording sheet

paper towel, recording sheet – optional
paper towels, paper plates (or
something to contain the mess), knife,

Tip:
The eggs will float! There will
be some of the shell exposed,
but as it sits in the vinegar, it
will soften.
Day 1:
• Obtain 3 clear, 8oz glasses.
• Place 1 raw egg (uncracked) in each glass and then pour vinegar in cups until
the egg is covered.
• Set your submerged eggs in a safe place.

Day 3:
• Remove eggs from cups, set them on a paper towel and dump out the
vinegar.
• Rinse the cups with water. Dry them and set aside.
• Holding one egg in the palm of your hand, gently rub your thumb on the
surface of the egg. The shell should start coming off. It will feel
like sand paper as it comes off. The grit will help remove the shell
over the entire surface so don’t wash your hands until you are
done. Repeat this process with the other eggs.
• Rinse the eggs and wash your hands.
• Set up the demonstration: In one cup pour about 6 oz. of water and 20-30
drops of red food coloring. In another cup pour about 6 oz. of
your chosen alcohol. In the last cup pour about 6 oz of water.
Label glasses.
• Make observations if desired. Add eggs with removed shells.
