Book Description

7 and up

One look at any of these gadgets you can make, and your friends will call you a mechanical genius—or a mad scientist! Build a rocket-propelled toy car or a secret place to hide your treasures from snooping little kids. Grow a pumpkin so big, even an adult can’t lift it. Make an automatic dog feeder, a mechanical snowball thrower, or some storm-predicting bells. All fifteen “Amazing Stuff” projects produce toys that are more than playthings. Yet all you need are some pieces of wood, nails, oatmeal boxes, jar lids, and Popsicle sticks. And you just use a hammer, screwdriver, and other tools from around the house—plus a couple of cheap electric motors you can buy at any electronics store.  



Editorial Reviews

From School Library Journal

Grade 5–8—The 20 projects in this collection range from a simple "Heartbeat Monitor" to a fairly complex "Moth-Bot," a wheeled vehicle that moves toward light with the flick of a switch. Most have strong kid appeal, though the "Snowball Launcher" and "Super-Duper Water Shooter" are likely to generate more interest than the "Drinking-Straw Dispenser." Energetic writing makes all of the projects sound intriguing, and the process of creating working gadgets can be as much fun as the end result. Instructions are written in an engaging, conversational tone, with background information about concepts such as gravity and electricity woven into the text. The directions are fairly easy to follow, although the complexity of some of the later "contraptions" will require especially careful attention and possibly adult consultation. Diagrams are also helpful; several steps are often combined in a single illustration, but clear and consistent labeling makes them effective. Most of the projects use household materials, along with basic craft or electronic supplies. The last seven involve electricity; they are more complex and require more purchased items, such as DC motors and transistors. Fifteen of the projects have a clearly highlighted "Adult Supervision Required" note, mainly for use of drills, saws, or other sharp tools. This is a good resource for students looking for out-of-the-ordinary science projects and for curious and creative kids who just want to make something fun and different.—Steven Engelfried, Beaverton City Library, OR

From Booklist

"Does your arm get tired and start hurting right in the middle of a snowball fight?" The solution to these and other conundrums (how to get maximum range out of a water shooter; how to turn a toy car into a rocket) are presented in this accessible selection of projects, many of which have appeared in magazines such as Boys' Quest and Hopscotch for Girls. The open layouts present diagrams and step-by-step instructions for projects that include a giant-pumpkin grower, a stethoscope, and a robot, and the author encourages kids to use recycled materials, such as empty oatmeal canisters and paper-towel tubes. Fox also discusses the scientific principles each project demonstrates, making this an excellent choice for classroom use. Younger kids will need help with both the science facts and the tools (notes indicate the projects requiring adult supervision), but older ones can confidently tackle several simple contraptions on their own. Adults will welcome this selection of high-interest projects that are ready-made for collaborative, educational fun. Gillian Engberg

More About the Author

I have always been a contraption fiend, at least ever since I made my first one when I was around 11. It was an electric buzzer that I got the idea for from the World Book encyclopedia. I was simply amazed by how the knife (which is one part I used to make it) vibrated back and forth continually when the battery was connected. I was hooked on contraptions at that instant and have been designing and making them ever since! If a kid is hooked on making contraptions what do you think he will want to do in later life? Of course become an engineer and design more contraptions! And I did just this! I received my Bachelor degree in Electrical Engineering from the Illinois Institute of Technology and, with the help from a NSF Fellowship, also got my Master's in Electrical Engineering from the same college. The first contraption I designed that appeared in publication was a Thunderstorm Alert gadget which received a front cover position in the September 1973 issue of Popular Electronics. This was the first of a long list of articles which appeared in nearly every general interest electronics related magazine around. And back in the 70s and 80s there were a lot of them! However, once you get the writing bug it grows on you so my writing life wasn't limited to contraptions. I also wrote for a multitude of magazines including Boys' Life, Organic Gardening, Michigan Out of Doors, Flower and Garden, Mother Earth news, Back Home, National Gardening and others. I also wrote two other books: Unique Electronic Weather Projects and Programming and Customizing the HC11 Microcontroller. I am now writing a column for both Boys' Quest and Fun For Kidz magazines. What type of column? You guessed it! A Workshop Column!

Since one gets really, really hungry putting together contraptions, I had to have a place where I could grow luscious food like fresh sweet corn and tree ripened peaches. So one could say it was my stomach talking that got me into the fresh fruit and vegetable business. You see, my family and myself , operate Magicland Farms Roadside Farm Market where we only sell what we grow ourselves. Who are in my family? My wife and six of my kids. What do I do on the farm? Well I use a bunch of contraptions like tractors, planters, harrows, cultivators, plows and on and on!

This review is from: Snowball Launchers, Giant-Pumpkin Growers, and Other Cool Contraptions (Paperback)
Cool Contraptions is exactly what you'll find in this book. Easy to follow directions with the lists of everything you will need before you get started.

I plan to use this for school projects and know that my children will feel pride in knowing they actually did it themselves!

Wow ! What a terrific book, jam packed with fun and exciting things to do. Projects range from simple to a little challenging ,but very "doable", really a great book for any age. We use this for our homeschooling for science, crafts and fun. I also think it will make a great Christmas gift for my 13 year old nephew.
The book also is easy to use with a great layout , and clear instructions, nicely done..
enjoy your giant pumpkin , but don't forget the "super-duper water shooter"!!
