Start your review of Nick and Tesla's Secret Agent Gadget Battle: A Mystery with Spy Cameras, Code Wheels, and Other Gadgets You Can Build Yourself (Nick and Tesla #3)
Recently, I've been trying to read all of the print books that I own. I live in a small two bedroom apartment, and they're slowly starting to take over my apartment. I own the whole Nick and Tesla series in print, so I've been trying to make my way through that so I can give the books to kids that I know will enjoy them, and do the experiments/projects in them. I recently finished the third book in the series, Nick and Tesla's Secret Agent Gadget Battle. I thought it was just an okay read.

This is my favorite book in this series thus far. It is because I have imagined myself as a secret agent many times and wondered what it would be like. Of course, I am one of the best agents around...well in my dreams anyways. So read about Nick and Tesla trying to uncover the mystery of the stolen necklace was fun. In fact, I mind this time actually break down and make the gadgets in this book along with my nephews.

I always love the drawn out picture of the elaborate plan on how Nick and Tesla

Good fun for its target age range. 11-year-old twins Nick and Tesla (ha ha) are staying with their distracted inventor uncle Newt (ha) when they discover that something nefarious is going on. Their house is under surveillance, their belongings start to disappear, and a bunch of suspicious people show up. But which one is the spy? Or thief? Or both? Nick and Tesla build several spy gadgets (and show you how to build them too) to help solve the mystery.

The gadgets are fun, although some don't look

Nick and Tesla are back at it again in this third story. They know that someone is spying on them and they have loads and loads of suspects. Is it their neighbor Julie Casserly? She is always fussing around her yard and some of Uncle Newt's inventions have done damage. Her garden gnome will never be the same. Or is it Mr. Jones who is Uncle Newt's neighbor on the other side. Nick is suspicious of everyone they know in town from the lone police officer to the man who delivers the mail.

From the 11-year-old:

My favorite quote from the book was, naturally something Uncle Newt said: “I’m not sure they’d believe me,” he said. “I think I lost a lot of my credibility after I called about Bigfoot.” It’s funny because Uncle Newt was calling to say that he found evidence that Bigfoot was fake. But the police misunderstood and thought he was saying that he believed in Bigfoot. It was all a comedy of errors.

My favorite scene was when they were in the Newtmobile during a car chase, pursui

I recieved a free copy of this book in exchange for an honest review, so- voila! Here is my five star honest review!
Now, most people would think I'm a little too old for this book, now that I've started tentatively browsing through the YA section at the library. Personally, I think that you're never too old to read this book! In the third book of their series, Nick and Tesla are in quite the predicament. It seems they are being spied on, and Nick refuses to trust anyone. Then, when something i

After winning this book on Goodreads, I would rate it 4/5. Some of my thoughts while reading the book:

-I liked how Nick and Telsa are normal kids.
-I thought the drawings were cool.
-When the author alternated perspectives of the characters I found the story more interesting.
-I haven't tried all of the experiments yet, but the one I tried I loved.

-I think the word "suspicious" is used too often.
-Most of the book happened in just one day. I think it could have been a little better in s
I read this to my 8&11 yr olds, and we all liked it. We read this first, by mistake, so we are now going back to read the first two books. My kids generally don't like books without dragons or some kind of magic, but this was funny and kept their attention. Also, there are a few science how to projects inside that you can try to make yourself. Great idea! ...more

No matter which of Nick and Tesla's adventures you read, it is always a good time. Their friends Silas and DeMarco always find some sort of crazy stunt to attempt, and this time it is riding a bike down a slide and then jumping it over a mud pit that they have dug in the backyard. Uncle Newt is busy trying to perfect his latest invention, which is a vacuum cleaner powered by rotten fruit.

This is the third book in the Nick and Tesla series. If you enjoyed the previous books I think you will enjoy this one as well. It was an excellent addition to the Nick and Tesla series. They are fewer gadgets to build in this book than in previous ones, but I thought the story was better here.

The last book in this series ended with a message from Nick and Tesla’s mom, she basically told them they are being spied on. Now Nick is seeing spies everywhere. He thinks the new apprentice that shows up

I received this book through Goodreads First Reads.

As with previous installments of this series (which it is not necessary to have read prior to reading this one, although it is certainly pleasant to do so!) the story serves as a vehicle for the science gadgetry. I have no problem with that at all, seeing as it's great to encourage kids to enjoy science AND to read! The story is entertaining in itself, with lots of humor and fun characters both new and returning, and it can be read without makin

Thanks to the publisher for giving me this book to read in exchange for an honest review.


I want to get this out at the very beginning: I think the more I read Middle Grade the less I feel like most MG is for me. Maybe I'm getting too old in mindset, but I don't know. This feeling, unfortunately, spreads to Nick and Tesla. That being said, I don't think this review is going to be very long... because I don't feel like I have very much to say.

I read the third book in this new science-themed mystery series by “Science Bob” Phlugfelder and Steve Hockensmith. There are two parts to this book- one, a mystery story and the other, a few science experiment ideas and instructions. I’m assuming Science Bob did those, while Steve Hockensmith wrote the story. He’s the author of “Holmes on the Range” and “Pride and Prejudice and Zombies.”

The story was a not altogether unpleasant read, but at the same time I must say it was really, really poor cr

I'm a literature teacher, and my husband is Quality Director for a tool and die shop, so it probably won't surprise you that we don't often read the same books. This third installment in the Nick and Tesla series charmed us both. We will definitely be giving it to our nieces and nephews on the next "gadget-building day with Uncle Jeff."

This is the first Nick ad Tesla book that I've read, and I will definitely go back and read the first two. I appreciate that the kids are smart and self-reliant,

I won this book in a Goodreads giveaway. It's unclear who the intended audience is, but I'm thinking the reader should be at least 11-13 years old. It was a good story and had the unique inclusion of various experiments that the reader could try out for himself. Note that there is a warning at the beginning of the book regarding the how-to projects and how they involve "motors, hydraulic power, hot glue, booby traps and other potentially dangerous elements", that adult supervision should be empl ...more

My thoughts on the series:
This is a lot of fun. I am way out of the target age range, but I enjoyed the stories. Middle-grade detectives, crazy scientist uncle, and international intrigue all converge. The projects are the type that kids in the target group will enjoy—my (bright) third-grader can’t wait to try some out. The illustrations could be clearer for the technically inept such as myself. However, there are videos available, as well as other cool information, at

I won this book in the Goodread's First Reads Program. I was excited to win this book, because my nephew and I loved reading the first two books together.

This one picks up right where the second book left off. Nick and Tesla get a message from their mom that cuts off right before she can tell them who is spying on them. Now they are trying to figure out who is spying on them, and why that person would want to spy on a couple of kids living with their crazy uncle. There are five more experiments

It’s the third volume of the Nick and Tesla series. The fun is still there and the science projects are equally fascinating. At the end of volume 2 Nick and Tesla receive a message from their mother. The phone call is cut off but she manages to warn them that someone dangerous is out to get them. Then strange things start happening. The message disappears off the answering machine. Uncle Newt hires 2 house cleaners and a pest inspector who just happen to leave advertisements on his front door. C ...more

Great concept! Science/engineering projects for kids + good story writing = a winner!

This is the first book I've read by Bob Pflugfelder, but I really would like to read the other books in the series now. The projects are not too complex, but they are still interesting. And the plot was a mystery that kept me interested -- it didn't feel like it was too contrived or just a thin string connecting the projects.

Overall, this book reminded me of the books in A Series of Unfortunate Events, with a sl

I received this book from Quirk Books to review. This is the third book in the series that my son and I have read. My son is 9 years old and loves this series and he was excited when we received it. He read the book first and he told me that it's his favorite one in the series. He especially likes the instructions in the book for whatever gadget they are making. After he finished the book I was able to read it. It was a great story and I kind of suspected who the spy in the book was but the way ...more

Nick and Tesla are clever and loyal siblings who are spending some time with their scientist grandfather while their parents are on a boring-sounding business trip. But of course everything is not as it seems! A strange call from their mother makes it clear that her trip is related to something dangerous - and that Nick and Tesla may be in danger too!

After getting a phone message from their mother warning that a spy is after them, Nick and Tesla find their uncle's house full of suspects. Who is the spy?

Another fun book filled with a great mystery, good characters, and a few laughs. The target middle grade audience will love it and enjoy building their own spy camera, code wheel, and more after they've found out who the spy is.

NOTE: I received this book via Amazon Vine in exchange for my honest review.

Another great story for Nick and Tesla. In this adventure they are trying to find out who is spying on them. The authors provided us with a handful of very humorous possibilities. I loved watching Nick and Tesla try to figure out each and every one of them. The techniques they used and the gadgets they build have instructions that are very easy to follow once again. It was a perfect mix of fun and education. My 11 year old daughter is loving this series as well.

Further into their wacky summer at their Uncle Newt's home, the twins realize that there is a spy in their midst that has something to do with their parents' mysterious scientific work for the government.

I received my copy through the Goodreads First Reads giveaway.

This series is really building up steam. It's going to be exciting to see where they will take the series in future volumes, as this installment finally answers some questions we've had since the beginning. Cool projects (I'm sure parents will be thrilled with the spy camera, and I'm sure kids won't care :) ), mysterious maids and more banana-fueled vacuum fun! Honestly, what more could a kid ask for?
