Above are the materials needed for this simple yet way cool craft/science project.
Below you can see the pipe cleaner snowflake the kids came up with. Any design will do.
All done! It didn't take our crystals long to form. Really just a few hours NOT overnight like the directions say. And if you aren't careful and watch your snowflake, it will grow too large to get out of the jar!
You can find the complete directions and a scientific explanation here.
We hung our snowflakes from the light over our kitchen table. However, these beauties would make great Christmas tree ornaments or window sun catchers too.
