Two scientists with a secret time travel project find themselves trapped in the time stream and appearing in notable periods of history. To find the cache and save the scientists you will need to bend time and find the faulty reactor tube in the tunnel. Beware tunnel may be flooded at times. No need to removed reactor tube or you may get trapped in time, just carefully unscrew the cap to save the scientists. Bring your own pen to take notes, pathtag and FTF coin for first to arrive in time.
Difficulty of final will vary depending on time of year and recent weather.
