FishyFish Sep 29, We love jokes, FishyFish! Thanks for giving us a laugh today! Gonzalez McTaco Sep 28, Black light sounds cool. Please love me again Wonderopolis. That's great, B.
We hope you'll come back and share what you learn! Sep 28, This is cool! Black lights can also be used to reveal hiddes messages from writing in invisible ink. The pen usually has a UV light on 1 side and a invisible ink pen on the other side. Invisible ink can be various stuff. It can be made from lemon juice to milk. Some versions invisible are visible at a right heat while others are resistant to everything except the black light or other revealer like melted pomegranate juice so the message comes through while the rest of the paper or surface is hidden.
Hop this was helpful! Thank for the suggestion wonderoplis! You're welcome, Gabriel! Ilumminati Sep 28, I have a blacklight. I use it sometimes. Once i took a blacklight to my uncles house and saw a ton of scorpions!
They all glowed! Whoa, that's interesting, Ilumminati! Thank you for sharing your connection to this Wonder. We're glad you liked this Wonder, jackie! Thank you for stopping by Wonderopolis! Bee Sep 28, I think this link is very racist on so many levels. I think you should take down this link because it is racist and that is all for now but just know I'm always going to be here on this wonder thing so good day to you sir!
Isabel Sep 28, That was cool to learn about how black lights work. We're glad you liked this Wonder, Isabel!

These various forms of luminescence differ in their method of emitting light. Chemiluminescence is the emission of light caused by a chemical reaction. This type of luminescence can be observed by bending and shaking a light stick. Inside the light stick is an encapsulated chemical solution, surrounded by a different chemical solution. Bending the light stick causes the encapsulated chemical solution to break open. Shaking the light stick then causes the two solutions inside the stick to mix.
When these chemicals combine, energy is created in the form of light. Organisms that emit light, known as bioluminescent organisms, also produce light through a chemical reaction. Phosphorescence is the ability of a material to absorb energy from an electromagnetic radiation source, such as a flashlight, and then continue to emit light after the source has been removed.
In this activity, the glow in the dark object absorbs or stores the energy from the flashlight and then gradually re-emits the energy as light, even after the flashlight has been turned off. Fluorescence is similar to phosphorescence, in that it is the ability of a material to emit light by absorbing energy from a source of electromagnetic radiation.
However, unlike phosphorescence, fluorescent materials can only emit light during the time that they are exposed to the source of electromagnetic radiation. Extended Activities and Links Have each student research a bioluminescent animal and create a presentation that includes its habitat, diet, and how it uses its bioluminescent ability to survive.
Include photos or illustrations of the bioluminescent animal to share with the rest of the class. Create a mural of an underwater scene that represents a variety of bioluminescent sea animals. Make sure to review with students the difference between paint that glows in the dark a type of phosphorescent material and bioluminescence, which is caused by a chemical reaction. Consider a field trip to a science museum or mineral show to see fluorescent minerals.
This lesson plan was created by the New York Hall of Science in collaboration with Science Friday as part of Teachers Talking Science, an online resource for teachers, homeschoolers, and parents to produce free materials based on very popular SciFri Videos to help in the classroom or around the kitchen table.

There are lots of natural phosphors, in your teeth and fingernails, among other things. There also a lot of phosphors in manmade material, including television screens and some paints, fabric and plastics.
Most fluorescent colored things, such as highlighters, contain phosphors, and you'll find them in all glow-in-the-dark products. Clubs and amusement parks use special black light paint that glows different colors.
You can also buy fluorescent black light bubbles , invisible black light ink, fluorescent black light carpet and even fluorescent black light hair gel. In addition to making people and fluorescent posters look cool, black lights have some practical applications.
For example:. Most of these uses, as well as dozens of others, follow a common theme -- the black lights make the invisible visible or isolate one specific substance from everything around it. When you think about it, there are dozens of situations where you could put this phenomenon to work. The applications are potentially endless!
