The guide describes how fluorescence occurs after absorbing light energy (such as UV) and releasing visible light as photons within seconds. It lists materials and safety rules, then provides step-by-step instructions to transform a flashlight using tape and colored markers to observe which household items fluoresce. Suggested items include milk, ketchup, bananas, oranges, and spices.","Black Light Experiments  \nAbout the Experiment  \nLuminescence is a source that gives light without heat. There are many different types of luminescence. In this experiment we will be looking at Fluorescence in food and plants. Fluorescence is an optical phenomenal that occurs when the atoms inside a fluorescent material become excited after  \nabsorbing light energy (such as UV-light) and the material emits visible light. The visible light is emitted as the energy of the material are returned to normal. This all takes place in less than a second. The visible light given off are tiny particles called photons.  \nAges – 5-12  Time – 15-20 minutes  \n Difficulty – Easy  \nWhat You’ll Need for the Experiment  \n• Scotch Tape  \n• Flashlight (can be $1 flashlight)  \n• Blue and Purple sharpie pen  \n• 4-5 food items (orange juice, organic honey, milk, eggs, olive oil)  \nLet’s Do This!  \nMaking your own black Light  \n*Safety-Never shine a UV-Visible light directly into your eyes or the eyes of other people or animals.  \n1. Place a layer of tape (2-3 pieces) over the flashlight lens all in the same direction. Make sure the flashlight is off.  \n2. Color the layer of tape with the blue sharpie  \n3. Place a layer of scotch tape perpendicular (90°) to the layer of tape you placed in step 1  \n4. Color the layer in step 3 with the blue sharpie  \n5. Place another layer of scotch tape perpendicular to the layer of tape you placed in step 3  \n6. Color the layer in step 5 with the purple sharpie. Turn on your flashlight, which has been transformed into a fluorescent light!  \n7. Observe the Fluorescence of Food and Plants  \nUsing the UV-light you just made, look at the fluorescence of different food items and plants around your house and yard. Some items will show fluorescence and some items will not. Below are some pictures of fluorescence of items and a list of some items that will fluoresce.  \nOther things to try  \n• Milk  \n• Ketchup  \n• Bananas  \n• Oranges  \n• Spices","cbCaicswcqCbO4Bn","https://ap.wps.com/l/cbCaicswcqCbO4Bn","pdf",828065,2,1,4,"English","en",105,"# About the Experiment\n## What You’ll Need for the Experiment\n## Let’s Do This!\n### Making your own black Light\n### Observe the Fluorescence of Food and Plants\n## Other things to try","[{\"question\":\"What causes fluorescence in this experiment?\",\"answer\":\"Fluorescent materials become excited after absorbing light energy such as UV light, then emit visible light as the energy returns to normal.\"},{\"question\":\"How do you make the black light from a flashlight?\",\"answer\":\"Cover the flashlight lens with tape layers, color them with blue and purple sharpies, stack perpendicular tape layers, then turn on the flashlight to create a fluorescent light effect.\"},{\"question\":\"Which items are likely to fluoresce?\",\"answer\":\"Some household foods show fluorescence while others do not.
