Montreal planetarium seals messages in time capsule until 2050

MONTREAL – The Montreal planetarium has sealed a 35-year time capsule that includes 25 messages written by Quebec students.

Grade 6 students had to write a composition for their 2014 provincial French exams based on what life would be like in 2050.

The 25 letters are addressed to children of the future and were picked from 77,000 entries.

They were placed inside a stainless steel capsule Tuesday, along with other artifacts, including a 1966 brochure from the city’s old Dow planetarium.
