This book is so good, that after 20 years since reading it, I remember the joy it brought me. As a young reader, the Danny Dunn books opened up a whole world to me.

Danny Dunn was my introduction to the excitement and wonder of books and turned me into a voracious reader. In this book Danny once again acts without thinking and creates a substance that will defy gravity and send a space ship (and himself as well) into outer space. Delightful and intriguing.

I'm shocked these books are out of print. I totally enjoyed them and I think I read every one. This book especially was practically prophetic from the standpoint of what the military is currently working on. Consider the year written, and it is quite remarkable.

I would highly recommend this book for young kids interested in imaginative inventions. "Creative inventors", so to speak.

Danny, loooooooong preceeding "Neuromancer", dons a helmet and gloves which give him sensations from an outside source--in this case, a mechanical dragonfly. He uses this technology to his own ends, of course. Prescient sci-fi from the team of Williams and Abraskin.

Even though I read this book a little while ago, I remember it being good. I liked the whole book, especially the end and the middle.

Danny, Joe, Professor Bullfinch, and, yes, everyone's favorite, Dr. Grimes, are stranded on an island when their plans go wrong--their plans to be stranded on separate islands! Old-school storyline, new Danny twists. And plenty of great Joe lines, as I recall.

It wasn't one of my favorite books to read. Too boring. I mean, Danny D-... zzzzzzzzzzzzzzzzzzz Oops sorry. Just an example what I did while reading the book.

The Danny Dunn series was definitely the most popular science fiction books for children during the 1960's.

If I remember the storyline correctly, Danny Dunn was a teenager(?) who lived with his mother who worked as a livein housekeeper for Prof. Bullfinch, an inventor. The Professor was a father figure and mentor for the young Danny.

Each story centers around some new invention that the Professor has invented and the adventures that Danny gets involved in along with his best friend Joe and girl friend Irene. (If I remember the names correctly.)

Unfortunately, the "science" of these books is a little outdated since some of the inventions that appear (like a personnal computer in "The Homework Machine") have moved from "fiction" to "fact". Still, it was a very enjoyable series and I would love to see them back in print.

The "Time Traveler" story is very similar to the storyline of the "Back to the Future" movies. Prof. Bullfinch invents a time machine which transports his entire house, along with the Professor, Danny and Joe inside, back to the 18th century and it appears in the backyard of Benjamin Franklin. Unfortunately, since there is no electricity coming to his house in the 18th century, the Professor cannot power his time machine to take them back to the future. They enlist the help of Benjamin Franklin and ... well, you can guess what happens next.

Well, the culmination of a project, anyway. The whole gang (Danny Dunn, Irene Miller, Joe Pearson, Prof. Euclid Bullfinch, Dr. A. J. Grimes) accompany another scientist to England, where he has secured time on a radio telescope, to listen for interplanetary radio signals. They have the usual mishaps, but Danny comes through in the end when a message comes in, and figures out how to decipher it. What does it say? That, you'll have to find out for yourself.

The Professor goes on the road, and so naturally, Danny, Irene and Joe tinker with his latest creation. When they discover some of its capabilites (like creating thunderstorms in the kitchen) they think they have a new weapon in their ongoing battles with Eddie "Snitcher" Phillips.

Instead of using sound science, explaining it, and sometimes extending it like in the other fourteen books, this one stoops to one of the oldest premises of B-movie sci-fi - and it isn't even scientifically sound.

Just because it's easy to shrink people on screen doesn't make it possible. Particularly the way it happens here - accidentally falling in the machine, getting dismantled, and waking up in a compressed duplicate (with the originals still in the machine) and then being able to reverse the process and coming out exactly the same size they were before! How did they even survive dismantling? Even if the process worked how were they able to walk?

The whole premise just shakes me up, even twenty years after first reading it. (Might be all those movies and Hanna-Barbera cartoons.) The only reason why I give this two stars is the familiar, endearing characters.
