3 Tbs. borax
1 cup water, boiling
large glass jar
Shape the pipe cleaner into any desired form, such as a heart, star or Christmas tree.
Attach the pipe cleaner shape to a pencil with string.
An adult should carefully mix borax and boiling water to create a solution that will form crystals on the pipe cleaner. Up to four cups of water will likely be needed to fill a large jar, so mix accordingly.
Dip the pipe cleaner into the solution and let sit overnight, suspended by the pencil and string (figure A). In the morning, the pipe cleaner will be transformed into a unique ornament that looks great on gift boxes or on the tree.
