Explosion in science classroom injures 7 students
CARLISLE, Pa. (AP) - A small explosion and fire Wednesday in a central Pennsylvania eighth-grade science classroom required hospital treatment for seven students and a teacher.
Carlisle Area School District Superintendent John Friend told reporters that a fireball occurred when some sort of chemicals were mixed together. He said that the teacher put out the fire with an extinguisher, WHTM-TV reported.
Cumberland County public safety spokeswoman Meg Silverstrim said two of the injured children were taken by helicopter from Wilson Middle School in Carlisle to Johns Hopkins Hospital in Baltimore.
Officials at Johns Hopkins said they could not provide information without the patients' names, which were not released.
A Carlisle Regional Medical Center spokeswoman said five students and a teacher were treated for what she described as minor injuries, and all six had been released by midafternoon.
The school continued with its regular day, Silverstrim said.

Calcium Chloride and water are fun. My 7th grade science teacher allowed us to light off the gas.
Â
With a CO2 bottle at the ready...
Â
He relaxed after a bit, but left the bottle handy if we felt things were going sideways. We were responsible miscreants.
 @WebFootSTi Yep we had a rather naive science teacher that used to let us stay after school and make stuff always explosive.
Â
We had lots of fun with the Iodine contact explosive and a much more dangerous contact explosive that I will leave the two simple items out so I am not sued 20,000 times as people blow there body parts off making it.
Â
It was great and fairly safe in a pill capsule size amounts and we made sure to never combine more then that at one time.
Â
The compression from the plywood just throwing a heavy 10lb rock on it was an amazing explosion that sent the rock and board 20ft in the air and nearly cost me months of work to fix my parents $1000 dollar wall of view windows right behind us on the patio:)
Â
Always wanted to take a quarter size pile with a piece of plywood over it and drive over to see what happened but we were to young to drive and luckily smart enough to not do it to others...
Hmm What happens when you mix Hydrazine with hydrogen peroxide..oh Boom...
what do you get when a science teacher bumps his head?....a janitor
 @Phuzz What do you get when a science teacher bumps his head, a big mallet so the students can knock down the bump!
The science teacher needs to re-take his chemistry classes before he blows up the whole dang school.
