This Just In: Dry Ice Burns Your Skin!
 
Somebody should have told this dickhead "science teacher."

Quote:
A casual teacher who wanted to demonstrate a scientific principle by inviting students to hold on to dry ice thought it would be a good learning experience, a NSW court has heard.

‘‘Some students obviously took the game too seriously and [held on] too long to the dry ice,’’ Damien Hilton wrote in an incident report after eight of the students suffered blisters and severe burns at Terrigal High School, in the NSW Hunter, last February.

Mr Hilton, 49, of Wyong, previously pleaded not guilty to 10 charges, including eight counts of assaulting a student occasioning actual bodily harm.

He was also charged with negligently inflicting grievous bodily harm and recklessly inflicting grievous bodily harm.

The evidence concluded at Toronto Local Court on Tuesday with a burns expert from Concord Repatriation Hospital telling the court contact with dry ice for at least one minute could cause scarring, while contact for more than two minutes could cause burns so severe that they could require surgery.

At least one of the students held the solid carbon dioxide for more than two minutes, the court previously heard.

In the incident report, which was filed after a number of students were taken to Gosford and Wyong hospitals, Mr Hilton wrote: ‘‘I thought it would be a good learning experience for the students to experience sublimation of dry ice.’’

Sublimation is the transition of a substance from a solid state to gas.

‘‘I had volunteers from the class come out and hold dry ice whilst another student timed them as a sort of game,’’ the report continued.

Photos tendered to the court showed a range of injuries from redness and swelling to large blisters and skin completely burnt from the students’ palms.

At the conclusion of yesterday’s evidence, defence barrister Stuart Bouveng said he would argue that the prosecution had not provided evidence that was capable of proving the assault charges.

Magistrate Jennifer Atkinson adjourned the case to April.

Has anybody got any similar stories of reckless endangerment in the classroom?

A teacher should know not to let stupid kids handle stuff that might be dangerous...

Kids are idiots.

Saying that, I don't know what age the kids are.

ErikLensherr 01-17-2013 08:42 AM

Why wouldn't you drop it if it's burning you? Dumb teacher, dumber kids.

H4T3BR33D3R 01-17-2013 08:43 AM

So the teacher knew the shit would burn and then let kids see who can hold it the longest?





Wow.... What a bright man. :haha

Who knows. It says "at least." Maybe it was a photo finish.

Dry Ice is, at its warmest, -78.5C. For "context" of how cold that is.

You wouldn't tell kids to hold some burning kerosene in their hands, would you. Moron.

That might not actually burn you, since it isn't the kerosene liquid burning, its the vapors.

This never occurred to me. Anyone got any kerosene knocking about?

My science teacher thought it would be responsible to pass around a test tube of ethanol while writing shit on the board. He was surprised when it came back nearly empty. I don't know what happened to it, I assume nobody drank it there because there was no screaming/dying, but I imagine it went into someone's drink bottle for later.

We had some fun with liquid nitrogen in physics; dipping our fingers in it (only for a split second), soaking rubber balls in it and smashing them, and storing tons of balloons in one thermos full of the stuff, like a balloon clown car. That stuff's pretty standard from what I can tell, though. Wouldn't surprise me if half the Pit did it in high school too.
Dry ice, on the other hand...

Ninja#117 01-17-2013 01:30 PM

THe teacher is stupid no doubt but WTF kids put that shit down if its actually burning you. I couldnt see myself watching and feeling my skin melt off and just taking it.

Why didnt they just drop that shit?

BeefWellington 01-17-2013 01:47 PM

I don't know who's more of an imbecile. The teacher should have known that was going to happen when you hold onto something that cold. The fact that he made it a "game" multiplies the stupidity.

The kids are even more idiotic for holding onto it for that length of time through the pain.

I've worked with dry ice in a lab several times and accidentally got some on my hand for a second or two. Even that was unpleasant enough to get a gasp and a sharp retreat of my hand. How stupid can you get?!

eGraham 01-17-2013 02:29 PM

How could anyone hold onto dry ice for two minutes? That kid deserves a medal.

obligatory lolcanadascience

TheChaz 01-17-2013 03:30 PM

What kind of dumbass kid severely burns his hands to win a game? Holy shit.
