AARHUS, DENMARK, (NBC) - A town in Denmark is conducting an experiment by putting young students in a 70's-style commune without modern technology.
The students packed their bags for a trip 40 years back in time.
Saying "goodbye" to 2014 means saying "goodbye" to modern luxuries, like iPads, as well.
They then moved into a second-floor apartment in a museum, which was fitted with the best tech available in the 1970's.
They'll have to live in the apartment for a week, and survive the best they can.
The four were chosen from a pool of several hundred applicants.
The apartment will be open to museum guests this weekend, to see how the students did.
They're sure to have a "groovy" time.
