Glo Germ™ powder is used to effectively demonstrate how germs are spread through cross contamination. One easy demonstration is to sprinkle Glo Germ™ powder on a work surface and then wash the surface. Residual "simulated germs" then show up a brilliant white under UV black light. A second demonstration is to sprinkle or brush Glo Germ™ powder on a fruit or vegetable and then cut it up. UV black light will show where the "glowing germs" have been spread from the produce to the knife, cutting board, and hands.
This is a great way to teach children the importance of kitchen cleanliness. Order with our economical UV black light, sold separately. One 4 ounce bottle is sufficient for hundreds of demonstrations.
