Indoor Fireworks

"I asked Tim to have a look at my hair straighteners"
"Why?"
"Because they aren't working, they've sort of...died"
"Right, and why did you ask Tim to do this?"
"Because he's an electrical engineer"
"Yes, to do with Helicopters, not hair straighteners"
"Well...you know" I shrugged my shoulders as Mike looked at me pathetically "Turns out it didn't matter" I continued
"How's that?"
"I blew them up!"
"You what?"
"I blew up my hair straighteners"
"How the fuck...."
"Well, I was poking around inside them, and you know what, they really don't want you to get inside hair straighteners, and Tim and I were trying to work out where the funny buzzing noise was coming from, and first I saw Tim hold the circuit board while they were on, and I was like 'oh is it ok to do that, you won't get shocked or anything?' and he was like 'no, it's fine', so then I decided to hold it, only I held a component which had metal on it, and I flew across the room! Tim was like 'was that hot, or shock?' and I was like 'ssshhhooock', it wasn't very pleasant."
Mike looked despairingly at me "You were fiddling around inside hair straighteners while they were on?"
"Yes"
He sighed
"Well, they had to be plugged in, because otherwise you couldn't hear the buzzing noise they were making"
He looked blankly at me
"I burned my thumb" I said looking sheepish "when it shocked me"
"Ok"
"Anyway" I continued "what was more embarassing was the fact that i'd just been boasting about how I was using a screwdriver with a PLASTIC handle on it, to avoid electrocution, after last time, with the plug at 223, when I decided to take a short cut and instead of screwing the cover back on the plug, just plug it into the mains, forgetting it had metal in it, and my hand was touching the metal, and I shocked myself. And then I go and touch another metal thing carrying electricity and STILL shock myself"
Mike looked at me with a withering look
"So," I continued not put off by this at all "Then I really, really had to find out what was wrong with them, and so i was poking around with the screwdriver having learnt my lesson, and suddenly 'BANG' and there were sparks, and smoke, and soot...."
Mike's eyebrows raised "You mean you actually blew them up blew them up?"
"Yes, and we had to check that it hadn't set fire to my rug or anything, but it was ok, it hadn't, but they aren't working at all now, there is no way they are ever going to work again. Tim looked at them and told me I'd managed to blow a transistor" I grinned "it's quite hard to do" I said proudly "and he said I was lucky, sometimes the ends fly off them when you do that, but it didn't happen this time"
Mike groaned
"Apparently I managed to cross two components with the metal of the screwdriver to short circuit it, something about a live one and a grounded one, which caused the bang and sparks."
"you're proud of this aren't you?"
"Well, if they weren't going to work before, they certainly aren't now, and I can add them officially to my list of things I've blow up: 2 hairdryers, a computer monitor, a printer, 2 tv's, a stereo, a hoover and a pair of hair straighteners" I grinned at mike, he gave me a blank look back.
"Another reason why you shouldn't be involved with electrics"
