MY PLAN:
I will use a light sensor from the high school science lab to measure the luminance (brightness) given off by the glow from Bluestar and Luminol. Light sensors give a number reading on a scale called "lux." This gives me a scientific way to compare the luminance readings of the two blood detection sprays to DISCOVER THE WINNER!!!

My Hypothesis: If sections of drywall soaked with 2ml of synthetic blood are cleaned after 1 hour using 5 different cleaning methods and sprayed with Luminol or Bluestar after 5 days, then the drywall sections sprayed with Bluestar will have the highest luminance readings measured with a light sensor.
