This is a diorama of Captain Nemo's Nautilus from the 1954 movie, "20,000 Leagues Under the Sea". The model is available in 1/70th scale from the Nautilus Drydocks. The display stand and water effects were all scratch built.
Water effects were achieved with crumpled plastic sheeting, clear silicone and water effects paste. A video of this display along with the building procedure is available at https://www.youtube.com/watch?v=iCQZ-QptQZg
