"Crazy Laboratory" is a science-based show hosted by Bruno. In this episode, Bruno demonstrates how to create a homemade black light using a transparent adhesive tape, a blue permanent marker, and a pair of scissors. He explains that black light emits ultraviolet light, which is not visible to the human eye but can interact with certain materials, causing them to fluoresce or glow under black light.
Bruno then conducts an experiment in his lab, showing the effect of black light on different substances. For instance, soap and a highlighter glow under black light, demonstrating their fluorescence. He also shows a paint that glows under black light, and a powder that reacts to create a shiny effect when exposed to black light.
Finally, Bruno performs an outdoor experiment to demonstrate the effect of black light on a larger scale. He shows a surprise to his assistant, which involves the use of black light. Bruno concludes the episode by encouraging viewers to try the experiment at home and invites them to send videos of their results.
1. The text is a transcript of a science experiment conducted by a lab coat professor named Bruno.
2. The experiment involves the use of a "black light," which emits ultraviolet light not visible to the human eye.
3. The black light is used to reveal fluorescent colors on various objects and surfaces.
4. The experiment includes the use of soap, a highlighter, and powdered soap. These substances react with the ultraviolet light to emit fluorescent colors.
5. A unique aspect of the experiment is the creation of a homemade black light using a cell phone's flashlight. This involves covering the flashlight with five layers of blue transparent tape.
6. The experiment also includes the use of ultraviolet light to attract animals at night.
7. The video ends with a surprise reveal that the assistant has created a larger scale effect of black light.
