Solar Death Ray

Here's a fun weekend project:

Enjoy the warning from the website:

The sun is bright. Don’t look at the sun or you will damage your eyes. Anything that focuses the sun will only make it more dangerous. The Solar Death Ray is dangerous. Don’t build one. I’m surprised I haven’t burnt or blinded myself yet. The fumes from molten plastic can’t be good either. Don't play with fire.
