Searching for Traces with the UV Lamp—A Light Spectacle

I would not have thought it possible, how much in nature glows or fluoresces so colorfully under UV light. You should definitely get a UV flashlight and then shine it around outside in nature or on vacation. You will experience your colorful wonder! Shine it in the garden, in the forest, in the park, illuminate vegetables, plants, mosses, lichens, mushrooms, stones, minerals, spiders, and woodlice. A glowing vegetable smiley or a creepy pepper? No problem with UV light! Even garbage can be tracked down in nature, and LED lights glow magically. What the beaches of the North and Baltic Seas have to offer in terms of color, you will find out in Sect. 6.2 on the topic of “nighttime color spectacle on the beach”. From my experience, a UV flashlight with a wavelength of 365 nm (UV A) is best (example: Alonefire X901UV 365 nm UV flashlight, reference: Amazon, approx. 35 €). It is reliable, durable, and rechargeable via USB. I always have this UV lamp with me on all my trips.
