Danny is soaring above Midston in a plane with his pilot friend when he catched sight of a man stranded in a field and helps rescue him. The man happens to be millionaire Gledway Pippit, who is interested in Professor Bullfinch's new heat ray -- but Danny and the Professor must prove to him that the invention can be useful. One afternoon, Danny's friend Irene is listening to her short-wave radio when she hears about a forest fire nearby. Danny realizes that the Professor and Mr. Pippit drove their cars in that direction. Soon the police spot the men -- but they are surrounded by fire! Danny things he knows how to rescue them and put the heat ray to practical use. But can he do it in time? Danny Dunn and the Heat Ray is the seventh novel in the Danny Dunn series of juvenile science fiction/adventure books written by Raymond Abrashkin and Jay Williams.

A mistake by Danny leads to one of the Professor';s most startling inventions—ISIT, the Invisibility Simulator with Intromittent Transmission—a dragonfly-like probe which could be piloted with a telepresence helmet and gauntlet gloves. They all get to try it out. Irene uses it for bird watching. Joe investigates a bee hive. And Danny discovers a bully plans to cheat in a spelling bee. But none of them realizes the ISIT has military possibilities—until a general tries to sieze it!

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! This is the first of the 15-volume Danny Dunn series and features the original cover by acclaimed artist Ezra Jack Keats. Look for "Danny Dunn on a Desert Island," the second volume of the series, coming soon from Wildside Press!

And will their teacher learn what's really going on with homework?
