So for a short film I'm creating over the summer I've written a scene in which the sea level rises really quickly, engulfing the coast and ultimately most of the land. I can tackle everything, apart from a scene where the main characters parents are trapped in an office block. I've purchased and started t construct an office block miniature roughly 20cm high, but I'm unsure how to make the water rise around it and which angles to use. Can anyone help?
