Ghost+Crystals+Marty

Materials: 1. Ghost Crystals 2. Water in cups 3. String 4. Food Coloring

Procedure: 1. Pour some Ghost Crystals into a container and fill this container with water. (If there are too many than divide the crystals into multiple containers) 2. When they are at the top take one out of the container and tie a string around it. 3. Pull the string and crystal out and in the water.

Ghost Crystals are formed from Polyacrylamide polymers. These polymers are not toxic but should be handled with caution. In its cross linked form it is highly water absorbing and forms a soft gel used in contacts. It can also be used as part of facial surgery. It has even been said that a man’s wife spread these polymers in their lawn of grass, and the next morning his lawn was full of ghost crystals. The polymers seem to bend light, but it is only because they are mostly water and the glass reflects the light. The polymers are made up of so much water that they seem invisible in the water. This is true even when they are colored. They can absorb weights of water hundreds of times more than their own weight. If you stick a toothpick in it would seem to float in the loop. These crystals have very similar composure to that of the actual water.
