Son of Flubber (1963)

Professor Ned Brainard's luck seems to be running out after his earlier mishaps with the elastic material known as "Flubber." Undeterred, he embarks on a new venture involving a gravity-defying substance he calls "Flubbergas." His ambitious experiments face setbacks from government interference, much to the dismay of his wife, Betsy. However, a breakthrough involving a football uniform that could enhance performance might just provide Ned the opportunity he needs to prove the worth of his incredible new creation.
