Solar Death Ray

Who doesn’t want a huge solar death ray?

All that’s required is a large Fresnel lens from a discarded back projection TV and a wooden frame (what could possibly go wrong?).

Simply direct the lens towards the sun and aim it at whatever you want to get really hot.

The Fresnel lens can be seen in the partially disassembled back projection TV below.

Of course with extreme heat comes pretty decent tea!

And also somewhat toasty popcorn!

Thanks to my friend Liam for coming round and helping build and test the solar death ray.
