Several teachers and staff spent the night under the stars and on the roof of Montgomery Village Middle School in Maryland.
Chopper 4 flew over the staff Friday morning.
The staff promised their students they would sleep on the roof of the school, if the students raised at least $500 for earthquake and tsunami relief in Japan.
In total, the students managed to raise more than $600.
The teachers finally came down around 7 a.m. this morning.
