The series was apparently created as part of the Space Race era effort to produce American scientists and engineers. The film delivers an instruction on force, how it can be used, various forms of force and how it can either temporarily adjust an object’s form or permanently alter it. The film was produced by Larry Yust (:25). The first segment uses a variety of tools such as a beach ball (:29) and a rope for a game of tug of war (:38) to demonstrate force. When both amounts of applied force are equal, nothing moves (:43). When one end of force becomes weaker; as a young girl drops to the sand during the game, (1:05) the center of the rope moves. A beach ball is rolled down the shoreline (1:13). When another group of (1:24) children applies force to the opposing end of the ball it stops. An athlete demonstrates the curve of the planets rotation around the earth (1:57) using an iron ball. A young girl and boy press together a beach ball to temporarily change its shape (2:35). Hands force a sponge together releasing water (2:54). A spring balance is used in demonstration (3:03). Another example utilizes coat hangers, rubber bands and a ruler (4:07). A paper clip is not elastic enough to spring back into original form if the applied force is great enough (4:12). Clay is pressed in a man’s fist changing it’s shape (4:46). Merry go round lights at a carnival flick on screen (5:04). The Strongman is visited as he bends a thick metal pole (5:24). A light and young girl steps onto a see-saw with the Strongman (5:48). She is still able to lift the Strongman (6:02) as well as his weights due to the aide of the see saw. She uses a jack to lift a 5 ton truck (7:01) with little force. A large vice snaps through a piece of plywood (7:11) again with little force. A young boy utilizes a hammer and wedge to drive into the center of a tree stump (7:52). Steel balls are swung against one another in order to drive the other in the opposite direction (8:59). Magnets are able to use force for movement without connecting with an object (9:45). Another magnet pulls up tacks from a counter (10:09). The film turns to electrical force (10:29). As the generator is turned on, an electrical force drags the balloons in towards the machine (10:38). Gravitational force (11:18) is demonstrated in a junkyard. A car is smothered (11:25) as a massive weight is dropped. The moon encircles the Earth due to gravitational pull (11:39). At a baseball game, the umpire looks to the skies as the ball soars high (12:28) and plummets down to tag a teammate out. Jet engines propel space jets into the atmosphere (12:47) with enough force to combat the Earth’s gravitational pull.
