The summary is:
The video is about a bioengineer who wants to build a meat laser, which is a laser made of living animal cells that produce fluorescent proteins. He explains how he plans to use a UV laser to excite a dye solution that can emit laser light of different colors. He shows how he built his own UV laser from scrap materials and how he adjusted the mirrors and lenses to make the dye laser work. He also talks about how he can use different dyes and diffraction gratings to tune the color of the laser. He says he has a collection of genetically engineered E. coli that can produce fluorescent proteins of various colors, and he hopes to test them in his dye laser. He also mentions that he is working on modifying mouse cells to produce green fluorescent protein, which could be used to make a meat laser. He ends the video by promoting an event where he and other creators will showcase their projects in person.
Here are the key facts extracted from the text:
1. The text is about building a meat laser, which is a laser made of living animal cells.
2. The text describes how to make a dye laser, which is a type of laser that uses fluorescent chemicals or proteins to emit light of different colors.
3. The text explains the theory and the components of a dye laser, such as the UV light source, the lens, the container, and the mirrors.
4. The text mentions some examples of fluorescent chemicals and proteins that can be used in a dye laser, such as rhodamine 6G, green fluorescent protein, and highlighter ink.
5. The text also talks about the challenges and dangers of building a dye laser, such as aligning the mirrors, finding the right concentration of dye, and avoiding high voltages and UV exposure.
6. The text ends with a question about attending an event called Open Source 2023, where the author and other creators will showcase their projects.
