Want to support this channel and help us preserve old films? Visit Visit our website To test designs of new Apollo spacesuits, and to understand the types of tasks that astronauts could perform in low or zero gravity, a large water tank was employed. This film shows SCUBA divers in the tank, negotiating using handholds on a grid which is made up of hexagons. A somewhat similar open mesh hexagonal grid floor was used aboard Skylab. Note: Footage from a closer camera can be seen in this related film: In the film, the diver climbs across the grid and then removed and replaces a handle-like device. The grid shown is also demonstrated to support toeholds, enabling the diver to have the leverage to lift and emplace the handle-like device over and over again. At 8:17, a diver attempts to secure a large case or instrument package to the grid, using the handle to hold it in place. It does not work.
