 * ABSTRACT**

The purpose of this experiment was to find the most durable mascara. Mascara is hydrophilic, so when sprayed with water it will go away. To conduct the 1st experiment a light probe was placed behind a sheet of saran wrap, with a flashlight held in front of the plastic. The light was measured by amount of lux. The results for the first experiment were 4063 lux for the first swipe of Maybelline mascara, 3553 lux for two swipes, and 2023 lux for three swipes. From this experiment it was concluded that Sephora mascara was most durable of the mascara tested.


 * CONCLUSION**

During this experiment many things were found. Most light came through when you had one swipe. The most durable mascara was the Sephora brand because the least amount of lux came through. The most mascara came down with the Maybelline brand. This experiment would be important to the world because consumers need to know what mascara is the best to buy. Also consumers need to know what mascara are most absorbent and what to not wear when it rains. Errors made in this experiment were the flashlight was not 100% steady, the applicators came on differently, the force put on the sprayers trigger affected the amount of water squirted and the mascara was in slightly different thicknesses. A follow up experiment would be to swipe different amount of mascara on a paper towels with different weights on them. The hypothesis was correct, it did have more light with more swipes of mascara.
