Materials:

• A Raw Egg
• Vinegar
• A Cup/Jar
• Food Coloring (optional)
• Access to a sink

Instructions:

1. Carefully, place your egg into the cup or jar.
2. Fill the cup with vinegar till the egg is covered. If you want a colored rubber egg, add some food coloring!
3. Wait and watch little bubbles form around the egg!
4. After 48 hours, take the egg out of the vinegar and gently wash the top layer of the egg off.
5. Have fun with your squishy egg! Your egg can bounce, and is even see through! Be careful though, because your rubber egg can pop!
