(With your parent’s help)
 
 Supplies:
 3/4 cup plus 2 tablespoons Alum Powder
 Egg
 2 cups of Hot Water (A parent should help with this)
 School Glue
 Paintbrush
 Food Coloring
 Small Glass or Mason Jar
 Scissors
 
Directions:

1. Use the tip of the scissors to poke a hole in the top and bottom of the egg. Then use the scissors to cut the shell lengthwise in half. Clean out the inside of the shell and pat it dry.
2. Use the paintbrush to spread glue in the inside of each half. Pour the alum powder onto the wet glue and spread it over the surface. Turn the shells over to remove any excess alum powder, then allow the shells to dry overnight. (The shells must be dry for the experiment to work)
3. When the glue is dried the next day, boil 2 cups of water. Pour ¾ cup of alum powder into the boiling water and stir until mostly dissolved. Divide the water mixture into two small cups or mason jars.
4. Drip 20 drops of food coloring to each jar and mix, then allow to cool.
5. Gently put each half shell into a jar and push it to the bottom with a spoon. Leave it for 15 hours.
6. Carefully take the shells out of the solution and place onto plate or paper towel to dry.

Look at what you grew in your egg!
