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!

Danny uses a computer that Professor Bulfinch has created for NASA to prepare his homework, despite Professor Bullfinch's warning that Danny is to leave the machine alone. With his friend Joe Pearson and his new neighbor, Irene Miller, Danny has some success with the machine before it is sabotaged. Can Danny figure out what is wrong with the computer and fix it? And will their teacher learn what's really going on with homework?

Danny, Irene, Joe, and Professor Bullfinch launch themselves on an amazing journey -- through time! They land in the year 1763 and one of the first people they meet is Benjamin Franklin. The Professor plans to return soon to the future, but when he throws the switch, the time machine won't start. While he and Mr. Franklin try to repair it, Danny and his friends explore the colonial era -- and Joe is kidnapped by an angry innkeeper who mistakes them for a runaway. Can the Professor get them back to their own time before more disasters happen? Danny Dunn, Time Traveler is the eighth 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!

By accidentally short-circuiting Professor Bulfinch's new crystalline material, Danny Dunn enables the professor to create a new machine that makes Danny invisible.
