Check Out This Backyard Solar “Death Ray”

NPR reports on a guy who built a potentially dangerous weapon at his home, using only a discarded TV and some spare lumber… and the power of science!

Grant Thompson shares his love of science-inspired weekend projects and life hacks at the YouTube channel King of Random. Last December, he posted a video of himself playing with a homemade Death Ray, which he calls by the slight more demure name, “The Solar Scorcher.” Using what looks like (and basically is) a four-foot-tall magnifying glass mounted on a hinged wooden frame, Thompson melts coins, ignites wood on contact, and boils water instantly.

Despite warning his viewers of the safety risks, Thompson doesn’t seem afraid to nudge a bottle closer to the 2000°F beam of light with his bare hand.

In another video, Thompson shows viewers how to get the large magnifying panel, which is a Fresnel lens from an old big screen TV that he got for free. The hardest part seemed to be loading and unloading the behemoth appliance.

Thompson’s nonchalant attitude adds a lot of appeal to the semi-scientific videos. His happy but matter-of-fact narration contrasts with the explosions and fire onscreen.

Thompson’s other videos include “Light A Fire With Your Pee,” “DIY Acrylic Fire Piston,” and “Make A Spot Welder For Cheap.” (Really? Aren’t there some things you shouldn’t skimp on?!”

What do you think? Would you want this thing at your home?

    I’ve been surfing online more than three hours today,
    yet I never found any interesting article like yours. It is pretty worth enough for me.
    In my opinion, if all web owners and bloggers made good content as
    you did, the web will be much more useful than ever before.
