Ready, set, grow! Creating your own colorful crystal
decorations is a fun way
to explore science with your child. This hands-on chemistry project is a simple and a ordable experiment that illustrates the properties of crystallization. Come learn with us!

1. Bendpipecleanersintodesiredshape.Werecommendmetallicpipecleanersinjeweltones for a more realistic gemstone look. Make sure to keep the pipe cleaner shape pretty tight so that crystals can form solidly. We created clusters of three pipe cleaners of the same color.
2. Attach shinglinetothepipecleanerclustersandmeasuresothattheclusterswillhang from the skewers/pencils leaving at least 1⁄2 inch of space on each side, giving the crystal room to grow.

Crystals can form when a supersaturated liquid that contains a dissolved mineral cools. In this experiment, a supersaturated solution was made using hot water and borax, a soft crystal. The hot water caused the water molecules to move further away from each other so that more of the borax could dissolve into the solution. Once the solution reaches a point where it cannot dissolve any more borax, it becomes supersaturated. As the solution cools, the
water molecules come closer together again causing the forming borax crystals
to cling to the pipe cleaner.
Crystal: a solid containing an internal pattern of molecules that is regular, repeated, and geometrically arranged.
Molecule: the smallest
physical unit of a substance
that can exist independently. A molecule is made up one or more atoms held together by chemical forces.
Supersaturated solution: a solution that has been heated in order to dissolve more material than would be possible at room temperature.
