Over the weekend, students dug up a bit of history at Iowa City High School.
They unearthed a time capsule buried 30 years ago by students in an anthropology class taught by Don Eells.
Inside were school papers and hall passes, knee socks and a 7UP bottle.
They also found some Pringles potato chips.
Student Jacob Yeates was brave enough to take a bite.
He says the antique chips didn't taste too bad.
The time capsule had a cassette tape that could be a recording of the 1978 students' predictions for the year 2000.
But Eells says they'll have dry out the tape to see if it can still be played.
