~20 years ago in college one of my best friend's had a 'break stuff' party in the basement of his off-campus house. The party goers took anything they could find around campus - things like discarded printers, etc - and destroyed them in the basement. Given it was a party, they also had lots of empty bottles of beer. The next morning, after spending some time in the basement cleaning up, one of the housemates came upstairs coughing blood. There were enough glass particles still in the air that he had inhaled some.
