Our microwave oven has reached end of life and its replacement is already sat in it’s place.
Before I take it to the tip, I’d like to conduct some scientific experiments on blowing stuff up in it, in incremental stages culminating in the, hopefully fairly spectacular, destruction of the appliance.
Obviously an egg is probably the starting point, but where to go from there?
Bowl full of thermite or go home!
I might not have any of that in the shed Chris… 
One of these inside might do the trick
I’d stand well back 
I once witnessed the aftermath of someone thinking “I am a student. I shall have beans on toast” while simultaneously having no clue.
He just shoved the unopened tin in the oven.
I would have thought that this scenario would be even better in a microwave.
Wasn’t there an episode of Brainiacs?
Ah,
See also another friend’s incident with a vegetarian haggis. That bastard went everywhere.
That would work too.
I think this would produce a lovely display 
.
A couple of weeks ago I wanted some molten wax to pot a small transformer in a case. I broke up some white candle, put it in a bowl & put it in the microwave. For ages (given the amount). It was very slow to melt. In the end I gave up, put the bits in a metal pan & melted it very quickly over a gas ring.
I was a bit surprised how feeble the microwave was at getting wax to melt. Not sure why that would be.
I think microwave ovens heat by exciting water molecules. I presume wax has a low water content.
I guess that’s right. They’re quick at melting butter but not plastic, tupperware etc.
Bar of soap
Sounds like Friday nights entertainment at lopwell is sorted. Extension lead by the fire pit at 9pm
Bring your own items 
What a fab idea.
Wow, what an utterly stupid thread.
I love it.
Eggs.
Several eggs.
Obv a stupid question but if it is at end of life why would it be capable of blowing anything up.
Next thing you know you’ll be conned into buying a horse 
FoL#2 is keen to destroy it at home, but with the amount of overtime she’s going to have to do to pay the instalments on her brand new (as of today) car loan (the loan is brand new, the car is very much not, and also another probable money pit) she might not be around to participate.
So Lopwell pyrotechnics might well be a thing.
We could all contribute an explody thing?
You buy it Rob and I’ll cook it.
Word is that if all else fails it might be possible to reactivate the getter in a gassy power valve by giving it literally a second or so in a microwave. It’s a bit hard to control the timing that precisely given that the magnetron has some heater warm-up time, but I did try it once. If anything it made bad gas worse. But the fireworks inside the valve were pretty. Transiently.
Otherwise maybe an oxy-acetylene mix in a balloon ? Or a few metallised plastic crisp bags ?
