  • In a previous project I found a free tv and turned it into a giant solar scorcher. This

  • shoots out a deadly beam of sunlight, that’s hot enough to abuse food, melt metal and burn

  • things you probably shouldn’t.

  • Today seemed like a good day to play with my Solar Scorcher. I positioned my frame and

  • found the focal point, then added some concrete tiles as a base for my projects. Ok, I've

  • got power, and I'll test it out with this piece of wood and when the light makes contact

  • I've got instant fire. The sunlight at this spot is around 2000 degrees Fahrenheit, enough

  • to melt this spot of concrete into a glowing orange liquid. I'm curious to see what I can

  • do with all this heat so I've filled a glass bottle with water and I'll punch a hole in

  • the cap. It's incredible to see that the instant I focus my lens on the bottle, it starts smoking.

  • Just a few moments later this water is so hot it's boiling, and I'm a little nervous

  • the bottle might blow. Yep, there it goes. The glass pieces are melting and that's cool,

  • but now I want to try this on some food. I'll get some hot dogs, and when they hit the beam

  • they really do get hot. This might be a little well done for my taste, and I'm still hungry

  • so let's try an egg. The egg is actually working very well. It's so reflective it doesn't burn

  • as fast, and even my wife is interested. A little salt and pepper and it's tempting to

  • try a bite. Ok, so I wasn't actually expecting to eat this, but it looks safe enough, and

  • even my kids are anxious to try. Surprisingly, it's pretty good. Alright, let's see what

  • else this will do. I'll try burning a penny, and, wow, it melted. How about a stack of

  • pennies? Yep, they're nothing but liquid metal now, and I'm thinking that slag in the mixture

  • must be what's left of the copper coating. It's only taking about 4 seconds to melt these,

  • and melting metal is really great, but now I want to see something burst. I wonder what

  • would happen to this egg? It's spewing some kind of debris and smoking like crazy. I hear

  • some little pops and it's even forming some interesting growths. huh, Look at that. But

  • no explosion. How about if I put a pop top on this bottle of water and let the pressure

  • build up? Yeah, that's what I'm looking for. Let's do that again. The lid is back on, and

  • pressure is building. Awesome! Alright, the sun is setting and I've re-adjusted my A-frame.

  • I'm just wondering if this would ignite gasoline. It does. Hopefully it goes without saying

  • that this is very dangerous and you shouldn't try this at home. Well, I'm convinced there's

  • an insane amount of power behind these lenses. If you'd like to see where I got this one,

  • take a look at my video on how I hacked it out of an old TV. This one boiled water in

  • less than a minute, welded a nickel to concrete, and instantly torched any piece of wood in

  • it's way. Well that was fun, but I'm still hungry so I'll put everything away and go

  • get some real home cooking. That's it for now. If you liked this project, perhaps youll

  • like some of my others. Check them out at thekingofrandom.com
