Brødrene Dal og Spektralsteinene

Brødrene Dal og Spektralsteinene is a norwegian tv series from 1982 and the second of a total of 4 series about Brødrene Dal.
The brothers are helping out in an excavation where professor Slatters is trying to find the 82nd curium. Unfortunately, the stones contain too much "umulium", making curium impossible to recover.
A creature from outer space gives the brothers the blueprints for a time machine, which they build and use to travel through time. The time travels take them to many different eras, where they among many meet Snorre Sprett, who wrote the king sagas. They also end up being the reason why the Suez canal was built.
