Those who know me know that I got my start in the internet from a Microwave. Many an hour was spent looking for things to microwave and what would happen to them when they went in. My friends. I have never tried something this dangerous, partly because I wanted to keep my microwave at a research level, and partly because the areas we engaged in our experiments were never as secure as that garage.
That being said, when I eventually get back into the greatest underutilized of the sciences, I will be sure to make a few pressure vessels to test out the security of my lab.
