A science fair project on how ink color affects eyesight might explore how different wavelengths of light, associated with various ink colors, are absorbed and processed by the eyes, affecting readability and eye strain. The project could involve participants reading texts in various colors under controlled lighting, timing how long they can read before experiencing discomfort, or testing recall and comprehension levels after reading. The science behind it involves understanding the eye’s sensitivity to light and color, photoreceptor activity, and how contrast and brightness influence visual perception. This experiment can highlight the importance of ergonomic color choices in educational and professional settings, potentially improving learning environments and productivity.

Creating a witch's broom with yarn is a fun and simple craft project, ideal for Halloween decorations or themed parties. To start, you'll need a small stick or dowel for the broom handle, and yarn in the colors of your choice. First, cut multiple lengths of yarn, all about 12 inches long, to serve as the broom bristles. Lay them out flat, then position the stick at the center, leaving an even amount of yarn hanging on either side.
Next, tie a separate piece of yarn tightly around the middle section of your arranged yarn pieces, securing them to the stick. This forms the bristles' base. For a more authentic look, you can fan out the yarn ends or trim them to create a uniform edge. Optionally, wrap another piece of yarn around the top part of the bristles adjacent to the stick to define the broom’s head better. This DIY witch's broom can be customized with different yarn colors and embellishments, making it a versatile craft for various occasions.
