By mixing art with a little chemistry, students create beautiful crystallized Hanukkah stars. Hang them in a window to catch the sunlight or on a door for decoration.
What You Need:
- Blue pipe cleaners, two per student
- Blue thread
- White string
- Pencils, one per student
- Plastic tub
- Boiling water
What You Do:
- Have students form two pipe cleaners into two separate, equally sized triangles.
- Students should place one triangle in front of them, with a point facing away and the opposing flat edge towards them. Have them place the second triangle on top of the first facing the opposite direction, with the point facing toward students and the flat side away.
- To hold the triangles in place and form the star, children should tie them together at intersecting points using thread.
- Have students tie a piece of string to the top of each star, then tie the loose end of the string to a pencil.
- Fill a suitably deep, narrow plastic tub with boiling water, then add Borax – one tablespoon at a time – to the water while stirring. For every cup of water, add 3 tablespoons of Borax.
- Have students hang their pipe cleaner stars in the tub so that the pencils rest across the top of the tub. The stars should be completely submerged, but hanging freely without touching the bottom of the tub.
- Allow the tub of stars to sit overnight, undisturbed.
- The next morning, the stars will be covered in crystals! Allow them to dry, then display.
