you've wasted several micro-cents worth or electricity.
AIUI the first thing to overheat is the glass platter.

Extremely unlikely to have caused any damage.
** Potentially, it can cause arcing in the wave guide leading to the oven enclosure. Then a fuse blows.
However, most microwave ovens are immune from the effect, but makers still advise never to do it. I happen to own one that isn't immune, a Samsung MB245.
I cannot use it to thaw a frozen bottle of lemonade, or it arcs up.

Its highly likely that any food spatter on the dielectric window that covers the end of the waveguide will carbonise and evolve a lot of heat and start arcing.
I've never bought a microwave new - I won plenty with arcing dielectric window - I just remove that and throw it away.
If you do that; don't do the exploding egg trick - a chunk of egg landed in the waveguide and the overload killed the mains transformer.
Its not free if you have to buy a dielectric window.
The last one got retired because the bottom rusted through where a wonky dish scraped through the paint, it was still going strong - which made it a leakage hazard.
I'm willing the current microwave to turn its toes up because there's a rather nice LG grill combo waiting to take its place.
Mine is a new Samsung ME73M.
What do you mean by 'arc up' ?

** A few seconds after the oven is switched on, a visible and audible arc s tarts up at the top of the wave guide - just behind the mica window. It qui ckly burns the paint in that area and the oven must be switched off immedia tely.ing on my doorstep when Samsung refused to replace it under warranty.
Powering up a microwave with nothing inside is an everyday event in busy ca fes.

I did hear a loud sound as soon as I switched the oven on while empty, which is the first time I switched it on. I wouldn't be surprised if the oven is damaged from what I did.
It seems crazy that just having the oven for a few seconds could damage it.

Yeah I know what you mean, though I do like Mythbusters (which is ending after
2016, by the way). Wikipedia says that Braiacs was shown on Go! in Australia, apparantly I decided not to watch it. If it's the one I'm thinking of (it might not be), it was a bit too hyped up for my tastes.You'd think YouTube would be a good platform for more "substantial" material, but I've had limited luck finding it.
Have you seen "The Secret Life of Machines"? That's my favourite. I've wondered why he never did microwaves though.

It's main purpose seems to be to showcase science to teenagers. in the form of 30? minute packages of of "Don't try this at home".
+1 from me.-- \_(?)_
I've only watched parts of an episode or two of mythbusters (usually until an ad break) and only by accident. I thought that, instead of just busting myths they were too muvch into 'the show'.
There is some good stuff but it does take some finding.
I hadn't seen it but have just started a torrent downloading [some of] the first season. I'll give it a look - thanks. :)

Meh.

I haven't seen the 2015 episodes yet but they dropped Grant, Tori and Kari for those and they went back to the original format of just the two of them. I don't think it worked.

Yep, watched a few episodes but soon got annoyed at the presentation style which is all hype and noise but very little substance IMO.
Not seen that one, will take a look.
There are some short postscripts for the episodes to cover more recent developments on the host's website:

Thanks. As soon as I started watching episode one I was taken back 40 years. I remember watching all the episodes (in series one at least) in my 20s and wishing I had a job like Tims. I've downloaded all the shows made and will watch them - and check out that site. Thanks again. :)
