Egg Experiment
Vinegar
2 eggs(1 for back up)
Container with lid
Water
two tablespoons of salt
rubbing alcohol or extra virgin olive oil
First, place your eggs in your container and fill it with vinegar until full.Wait two days without doing anything than on the third day open the lid and there will be a surprise! Once you've opened the lid take the eggs out VERY CAREFULLY(They will pop)dump out the vinegar and re- fill it with salt water (2 tblsp).Wait one day and on the second day take out the eggs and dump out the water and fill it with rubbing alcohol or extra virgin olive oil. The alcohol has a better/ more interesting result. Wait three days and the last step is cut your egg in half if you used the alcohol.

Crystal Gardens
6 Tbls. Salt
6 Tbls. Liquid Bluing
6 Tbls. Water
1 Tbl. Ammonia
Combine salt, bluing, water and ammonia. Pour over small pieces of rock or coal in a shallow GLASS or CHINA bowl. Drip food coloring on top if desire. Crystals will begin to grow soon. Add water occasionally to keep crystals growing. You'll probably want to place dish on tray or wooden board as crystals grow over the sides of the bowl.
