Hello everyone,
wanna make your own corals ?
Here's how to do it.

Materials you need :
-plasic bowls
-pieces of charcoal, porous brick, tile, cement, or sponge
-water
-table salt (iodized or plain)
-liquid bluing (found in bleaches at grocery stores)
-food coloring
-measuring tablespoons
-masking tape
-pens

Here's what you have to do :

1.Put some pieces of charcoal, brick, tile, sponge, or cement into your bowls.

2.Pour two tablespoons of water, two tablespoons of salt, and two tablespoons of liquid bluing over the base material (charcoal, etc.) Set bowls on a table or counter top. Formations need free air circulation to develop.

3. The next day add two more tablespoons of salt.

4. On the third day, pour in the bottom of the bowl (not directly on the base material) two tablepoons each of salt, water, and bluing, then add a few drops of food coloring to each piece of base material.

5. A crystal formation should appear by the third day. If not, it may be necessary to add two tablespoons of household ammonia to aid the growth. (Only adults should handle and add the ammonia). To keep your formation growing, just add more bluing, salt, and water from time to time.

6. The water, bluing, and dissolved salt combined to form crystals, coral polyps use dissolved calcium carbonate to create the stony cup that protects their soft bodies and creates reefs.

WOW!
I didnt know we could create "corals".
Until now.
