Cloud Tank Magic | Shanks FX | PBS Digital Studios

A cloud tank consists of a bottom layer of salt water and a top layer of fresh water and when various forms of liquid are injected into tank, clouds are produced. This was the common technique that Hollywood used for decades to capture supernatural weather. This video is a compilation of as many cloud tank examples as I could think of. I now ask for you guys to tell me what clips these movies are from, I’ll be checking the comments section pretty regularly for the next couple of days and will fill in the blanks when I see the correct movie in the comments section. 0:05 - 0:08 = Poltergeist 2 0:08 - 0:12 = Poltergeist 2 0:19 - 0:22 = Star Trek IV 0:29 - 0:30 = Poltergeist 0:31 - 0:32 = Close Encounters 0:32 - 0:34 = The Dark Crystal 0:34 - 0:37 = Ten Commandments 0:38 - 0:41 = Star Trek (The Movie) 0:41 - 0:44 = ID4 0:45 - 0:46 = Raiders of the Lost Ark 0:48 - 0:51 = Star Trek V 0:52 - 0:55 = Total Recall 0:56 - 1:00 = Ghostbusters 2 1:01
