Does the sun protection factor (SPF) make a difference? And how do different sunscreen brands compare? We recommend only leaving your sunscreen in the Solar Buddie for a maximum of 2 weeks.

Below the x-axis the wavelength ranges of Ultraviolet, Visible, and Infrared light are marked. The graph shows a larger peak between 250 and 1200 nanometers, with two smaller peaks in the 1200 nm to 2200 nm range.

The results of this science project told you how much sunscreen got from your pointer finger into the water sample—and the number might seem very small to you. However, you are not only putting your pointer finger in the water when swimming in the ocean—you go into the water with your whole body!
