A lack of control could result in the creation of some kind of music video, like the following, with a TV reporter interviewing several dissidents inside the Lab. Note that the reason this has never happened is because we are in control of ourselves, and not because KHS doesn't exist.
Reporter walks to one corner of the room.
"I see that you're training eight bunsen burners onto the middle of one test tube, here. Well, I say the test tube - it's more of a puddle on the desk. The desk laminate is dribbling onto the floor, closely followed by a trickle of molten glass. Is that supposed to happen? Why is your sink on fire?"
The young scientist makes no attempt to put out the fire, instead continuing to burn the test tube even further into oblivion. The reporter becomes dizzy, and starts to move away.
"Aha! Now here's an interesting experiment. You're investigating different mixtures of Lab juice, are you? Why's that one smoking? Oh it's meant to, is it?"
Reporter is hit by a blast of heat from the ignition behind him
"Wow! You've finally done it! You've created the worlds first SIX foot long Wall-o-Bunsens! I thought the floor was designed so that it DIDN'T melt while being bunsenned. The floor seems to be a steadily liquifying area of jelly around here."
The Wall-o-Bunsens cause the floor around them to melt, but it is nothing compared to the damage being done elsewhere..
"And you people are dropping weights, are you? Woow - that was close!"
A short, insane person drops a 20kg weight from eight feet in the air, whilst performing a desk stand. It smashes into the floor, causing many small cracks, and even more large ones.
"You'd better watch it here - I can hardly get past without the floor crumbling under my feet! Hey! You're having an ethanol fight! Oh no - you're just chucking it at the board."
A student rips the bunsen from it's tap and throws it across the room, hitting the board and lighting it from the excess heat, in the same movement. The board goes up in flames, fueled by the bombardment of flammable paper towels being hurled at it. A clump of fire falls down toward the floor, but it is put out by the growing puddle. A group of people had been doing laps, when they kicked over a bin which had been carefully placed under a tap, and was almost full of water. It had taken some force to knock it over, but the flying desk somersault had helped. Reporter leaves the board carnage...
"Oh good. The gas chamber is being put to good use. I suppose that's more smoke than gas, though. What's burning? Silver Nitrate? That's expensive as well! I didn't think it burned... oh... it doesn't - you've just superheated it."
Reporter feels heat from behind and sees a yellow glow fill the area, coming from the quad flame tube.
"Cool! The first fireball of the day!"
The fireball lights a student's book, which is lying on the side. Making no immediate attempt to put it out, he eventually does attempt to put it out by dunking it in a sink full of water. The sink, however, turns out to be full of ethanol instead of water, and ignites instantly. Seeing this, another student throws a test tube rack in there, to keep the fire going.
"Hey - we need that for the bonfire!"
Reporter turns around to face the bonfire, which is built several feet high, out of broken chairs, tables, and miscellaneous Lab equipment, and coated in a Lab juice starter mix.
"Hmmm. What's going on here? Electrolysis? But that doesn't involve fire? Oh... I see!"
The 12v electrolysis kit is whacked up to 240v, making sparks fly everywhere, igniting the overhead projector, which just happens to be covered in petrol. The picture that it projects would be better, was the wall not burned away. Liquid fire is projected onto the wall between cooling and melted plastic after the board fire, but then cuts out as the projector sparks, and explodes, leaving a cloud of grey smoke hovering around. A nearby ethanol coated desk goes up in flames as the bonfire annexes it. Suddenly, the bell goes.
"Damn! Is that it? Oh well... you know what to do!"
Two people kick over two drums of ethanol, which flood the wrecked Lab with waves of fire.
"Nice one. Hope that keeps the fire going until our next lesson tommorow!"
As you can see, even the reporter would probably be won over to the side of utter anarchy in the end. Still, it's a good job it never happened, eh?
