A chicken with red earlobes will produce brown eggs, and a chicken with white earlobes will produce white eggs. Look below to learn how to make a bouncy rubber egg.

Bouncy Rubber Egg

What you need
1 egg
1 jar
enough vinegar to fill your jar

Steps
1. Place a raw egg in a sauce pan and fill it with water.
2. With adult supervision bring the egg to a boil and cook for a further 10 minutes to make sure the egg has been cooked throughout.
3. Drain the boiled water from the pan and leave the egg to cool for a bit.
4. Gently place the hard-boiled egg in a glass jar.
5. Slowly pour in the vinegar until the egg is completely covered.
6. Screw the lid back on the jar tightly.
7. Keep checking your egg every day to see what changes are taking place.
8. Let the egg sit in the vinegar for at least one week.
9. After a week has passed; drain the vinegar from the jar. Rinse the egg under water and dry with a paper towel.

What happened to the eggshell?
The vinegar dissolves the eggshell and leaves you with a rubbery egg. Try bouncing the egg from a short distance; do not drop from a high height.

Fun fact: Vinegar has been around since ancient times.
