I'm passionate about exploring, experimenting, and sharing my findings. My books focus on creating engaging science toys using everyday household items like plastic sheets, polystyrene, drinking straws, rubber bands, and ice cream sticks. These fun and easy projects are designed to spark curiosity and inspire creativity, all while encouraging the reuse of materials. I hope these books will motivate others to recycle and upcycle, transforming discarded items into exciting scientific tools.
