YouTuber Known as Styropyro Created the Homemade Laser “Most Powerful in the World,” with 250 Watts — Capable of Cutting Steel, Burning Diamonds, and Exceeding 50 Thousand Times the Legal Limit in the U.S. Understand How He Did It.
A science fiction-worthy experiment has gained worldwide attention: YouTuber and self-taught inventor Drake Anthony, known as Styropyro, built what he calls the “most powerful homemade laser in the world.” With 250 watts of power, his “light weapon” can cut steel, melt tungsten, and even burn diamonds — all using parts purchased online and taken from old projectors.
The invention surpasses by more than 50 thousand times the legal power limit for portable lasers in the United States, which is 5 milliwatts. Even so, Anthony not only built the equipment with extreme technical skill but also documented the entire process on video, showing the world how it is possible to craft a laser with impressive destructive capabilities by hand.
The experiment has been deemed dangerous, fascinating, and — for science and engineering fans — absolutely inspiring. However, it also raises questions about safety, ethics, and the limits of homemade experimentation.

Who Is Styropyro, the Creator of the 250-Watt Laser
Drake Anthony, better known for his YouTube channel Styropyro, has been on the platform since 2006. He is a trained chemist but became popular for creating videos with extreme scientific experiments, ranging from super-powerful batteries to plasma weapons and giant lasers.
His approach is hands-on and often self-taught, marked by a practical style: he literally “got his hands dirty” dismantling used equipment and building new inventions with homemade tools. His content combines scientific education with technical spectacle, earning him millions of views and a loyal follower base.
The 250-watt laser project is the highlight of this journey — a proof that cutting-edge engineering can be explored outside official laboratories.
Understand How the Most Powerful Homemade Laser in the World Works
Styropyro’s laser is not made with a single light source. He used several high-power laser diodes, mainly taken from old movie projectors, which are known to contain powerful blue lasers. These diodes were aligned with optical precision, combining their beams using collimating lenses to form a single extremely intense beam.
The laser weapon operates with a total power of approximately 250 watts, enough to melt metals in seconds. In comparison, a typical laser pointer — like those used in presentations — averages 5 milliwatts, meaning Styropyro’s device is 50,000 times stronger than an average household laser.
Besides the raw power, the laser is solid-state focus, relatively portable, and uses a cooling system and power supply built with custom batteries. The design is made with a sturdy metal casing and a viewport with special filters — and, although it appears improvised, the level of precision and safety involved is surprising.
Is the Laser Legal? What Does U.S. Legislation Say
In the United States, the use and commercialization of lasers are regulated by the FDA (Food and Drug Administration) and other federal agencies. The legislation imposes a limit of 5 milliwatts for visible lasers to prevent eye injuries and misuse.
Lasers above this limit can cause instant blindness, skin burns, and even accidental fires. The creation of devices with power above 500 milliwatts is already considered critical — and Styropyro’s laser has 250,000 milliwatts (or 250 watts).
Although he built the device solely for educational purposes and used it in controlled environments and with appropriate protection, the very nature of the project is deemed “dubious” by American legislation. The YouTuber himself acknowledges the risk and potential illegality, which is why he has never used the laser in public areas or against human or living targets.
What Did the Laser Manage to Do? Impressive Tests
During video-recorded tests, the most powerful homemade laser in the world was put to the test in various situations. And the results are almost unbelievable:
- Melted tungsten, one of the most temperature-resistant metals on the planet
- Cut steel and aluminum, in thin plates and solid objects
- Pierced razor blades, demonstrating extreme cutting precision
- Burned small diamonds, through direct thermal absorption
- Melted alumina with chromium, creating synthesized rubies, like those produced in laboratories
- Attempted to melt snow, unsuccessfully — due to being highly reflective and thermally resistant
These tests are not just displays of power but real chemical and physical experiments, with high educational value for those studying optics, directed energy, and refractory materials.

Deixa a invenção fluir pq com certeza vai ser usado em algum experimento, esse jovem e promissor e merece apoio do governo
Pra fins militares é uma grande jogada ambiciosa para os engenheiros do Pentágono.kkkkl
Claro que devem ser permitidos!
Grandes cientistas e estudiosos nem sempre estão dentro de empresas gigantes ou em órgãos governamentais!
Isso demostra que gênios estão em toda parte, porém os governos sempre querem usá-los aos seus interesses, muitas vezes longe de ser em prol de seu povo!
