The lesson making a lasting impression at Tauranga Primary School this week is based around the prices of toys, models of the 1990s and atmospheric reactions of the decade.
This was after a photo clue and a few hole punches later led Tauranga Primary School staff to find a time capsule nestled into the wall of a soon-to-be-demolished classroom.
Principal Fiona Hawes said after finding a photo of the capsule being placed in the wall in 1993, staff made it their mission to find it - although it proved difficult after a new toilet block on the back made the spot unrecognisable.
Hence, the few hole punches later, she said.
