<human>: Last year during Spring Weekend at my school, the administration sponsored a big foam party, where two large machines would generate foam and spew it into bounce houses for all the kiddies to jump in. 

The line for this event was enormous, and it was supposed to be split into two (those who had purchased tickets beforehand and those who had not). Anyway, the gig was supposed to open at 10 pm, but the machines weren't working and they had to delay entry. All the people in the line were screaming "LET US IN" and I can say that at least half of them were either drunk or high. Eventually, the huge mob nearly broke out into a stampede, pushing through the barricade and racing towards the foam machines. Because the green is on an incline, hundreds of kids raced down the steps, many of them falling down and tumbling on the way. They had to bring in the cops.

Can you condense the text into three sentences or less?
<bot>: Crazy crowd in line for foam party goes out of control, bypass security and race towards foam in a drunken stampede.
