Rechargeable Regeneron ISEF Hand Fan

Stay cool while your ideas heat up. This lightweight, ergonomic hand fan features a whisper-quiet brushless motor with three speeds, so you can keep your cool without the noise. It rotates 180 degrees and props up on any surface, and the included carabiner clips right onto the silicone strap, bag, or belt loop for hands-free breezing. Charge it for 3 hours and enjoy up to 5 hours of airflow. Science is hot — you don't have to be.
