Old Kingdom era Magic Trick - Stacking Water or Parting the Red Sea

 Gelatin is a protein substance derived from collagen, a natural protein present in the tendons, ligaments, and tissues of mammals. It is produced by boiling the connective tissues, bones and skins of animals, usually cows and pigs. Gelatin's ability to form strong, transparent gels and flexible films that are easily digested, soluble in hot water, and capable of forming a positive binding action have made it a valuable commodity in food processing, pharmaceuticals, photography, and paper production.

Gelatin is a substance found in the bones, skins and other connective tissues of animals. It is normally present in soups, stews and gravies, where it occurs naturally from cooking the meat and bones. 

In the Old Kingdom of Ancient Egypt the Magicians (Lector Priests / "KheriHebs") (Westcar Papyrus) could "freeze the motion of water and cut & stack it on top of water to retrieve an item on the river floor."  The Hebrew Prophet Moses "parted the Sea of Reeds / Red Sea" using this method in the Book of Exodus.  

What they did was create Gelatin by boiling animal bones and pouring this heated mixture into the water until it solidified.  Then you could cut up and stack the water, part the seas, or walk on water.  To undo this they heated up water and poured it into the Gelatin until it became loose and watery.
