Spiropyran is a photochromic, organic chemical compound which undergoes physical changes in color when put under pressure or impacted by intense force. Using direct UV light, the energy of spiropyran samples was modified and observed using at-home lab set ups during the COVID-19 pandemic. A series of MatLab files were utilized to compute the percent activation of spiropyran with varying increments of light exposure. Different methods of impact were also used, including impact from hammer strikes and dropping the material from increased heights. The increase in potential for the use of spiropyran in medical and technological fields is an exciting prospect, and one which has the potential to branch into many avenues in the future.
