This document provides instructions and health warnings for an experiment involving blinking LEDs and magnets. It warns that batteries and magnets can be harmful if swallowed and the project should only be done under adult supervision. It also notes that the experiments are done at your own risk. The document then provides directions on orienting the LEDs correctly and adding magnets, and instructs to tape everything together firmly.
