**Title:** Building and Testing a 40W Laser Shotgun
**Summary:**
* The Backyard Scientist built a 40W laser shotgun inspired by Styro Pyro's video, using a modified Ruger 10/22 rifle stock, a circular saw trigger, a cheap adjustable LED driver, and an 8x 5W laser diode block from a movie projector.
* The laser is powerful enough to:
+ Ignite smokeless powder
+ Burn through leaves from 3 feet away
+ Damage a drone's propellers
+ Be visible over a mile away at nighttime
* The scientist and friend Nick Householder engaged in a "laser balloon-popping game" with the device, which Nick won.
* The video also briefly promotes Wix, a free website-building platform.
* The summary concludes with a teaser for a rematch using a remote-controlled laser turret, available on the scientist's channel.
