That's pretty cool actually. I was going to comment on the metal end cap, but pretty cool that the new microwaves will prevent the sparking. I've seen a few videos on youtube (they don't hang out long, as it violates their "standards"), but I've seen a few where the brewer put a huge quantity of all the ingredients in a container that had to equate to like half a gallon, and brewed it just like that. I forget what he was brewing up, it was awhile back, but thinking about it now, it was pretty mind blowing lol.
