Through a mishap in Professor Bulfinch's laboratory, Danny accidentally creates an anti-gravity paint. The natural use, of course, is for a spaceship -- the paint can replace rockets to get the ship into space. Unfortunately, the spaceship is launched prematurely after Danny and Joe follow Professor Bulfinch and Dr. Grimes on a tour of the ship. A mechanical failure dooms the four to a one-way trip out of the Solar System -- unless they can repair the spaceship in time!

As a boy detective Danny Dunn has lots of competition but the young scientist performs creditably here. Amateur sleuths are unlikely to lose any sleep over the crime or its solution: What could be a more obvious setup than an uncrackable safe? And who could be a more likely suspect than the store manager, Mr. Anguish, who asked Professor Bullfinch to design it? Yet the gadgetry Danny improvises would be the envy of any junior Sherlock; having learned the principle of Professor Bullfinch's watchdog safe (the owner's individual smell is its uncrackable combination) Danny builds his own radiometer from an old vacuum cleaner and is soon hot on the trail of the missing Mr. Anguish. With help from his pal Irene, occasional poetic encouragement from his non-scientist buddy Joe, and with fatherly, black Detective Ellison to keep their investigations in line, Danny keeps up a brisk pace. And young investigators will want to track down the pedigree of the Professor's chemical bloodhound. (Kirkus Review)

Another accident in Professor Bulfinch's laboratory, brought on by Danny, results in the creation of a transparent, resilient material. The material proves useful in creating a bathysphere, and Professor Bulfinch, along with his friend Dr. Grimes, Danny, Joe, and Irene, descends into the Pacific Ocean on an experimental voyage. Unfortunately, the bathysphere's pilot is rendered unconscious, and the bathysphere becomes trapped in a cave... Can Danny and his friends escape?Danny Dunn on the Ocean Floor is the fifth novel in the Danny Dunn series of juvenile science fiction/adventure books written by Raymond Abrashkin and Jay Williams.
