Disappearing Crystals®

One of the most entertaining and educational chemistry experiments is the growing of crystals, but what about growing crystals that appear and disappear?

A small glass or clear plastic jar appears to contain only water and a small string noose hanging down into the water. When the string is lifted out, a large shiny crystal appears tied in the noose. When the string is lowered back into the water, the crystal again disappears. That’s a Disappearing Crystal!
This activity comes complete with several small crystals, instructions and an explanation of the science connected with the experiment. The crystals are safe and non-toxic. Disappearing Crystals can be used over and over again for hours of wonderment and fun!



Teachers and home schooling parents, continually search for activities that will capture a child's attention and imagination. Disappearing Crystals will stimulate critical thinking as the boys and girls try to determine "why the crystals appear & disappear!" The interaction of these crystals with water can be used to teach basic concepts in light refraction and chemistry.

Disappearing Crystals have been used in science fair projects and magic shows. Also these crystals make ideal premiums for distribution by private school admission officials when they conduct open-house tours. Read how -->


ScienceIn ABag is a series of fun activities designed to get boys and girls excited about science and to stimulate critical thinking. Each activity comes complete in a bag.
