Son of Flubber

In this sequel to 'The Absent-Minded Professor', Professor Ned Brainard's discovery of Flubber has not quite brought him or his college the riches he thought. The Pentagon has declared his discovery to be top secret and the IRS has slapped him with a huge tax bill, even if he has yet to receive a cent. He thinks he may have found the solution in the form of "Flubbergas," (the "son" of Flubber) which can change the weather.
