If your children struggle with visualizing physical science, or if you are looking for a special treat for that child who thrives with hands-on instruction, you will find the Knex Gears, Knex Wheels/Axles & Inclined Planes, and Knex Levers & Pulleys sets quite suitable. Please note that due to the number of pieces, only one model can be built at a time.
The Knex Extravaganza is virtually an all-in-one set that is the largest, most complete set we have ever sold. It includes over 3,400 pieces and instructions for Knex Simple Machines, Knex Bridges Deluxe, and Knex Big Ball Factory!
With over 2200 pieces, Knex Real Bridge Building will enable your children to build seven different bridge types, each bridge 5 - 6 feet long! If you have the room, Knex Real Bridge Building has the wow. Models include some bridges from around the world like the Sydney Harbor Arch Bridge (Australia) and the Tower Bascule Bridge (London), plus local favorites like the Astoria Truss Bridge (Oregon) and of course the well-known Golden Gate Suspension Bridge (San Francisco). For a smaller bridge set try Knex Intro to Structures.
Knex DNA makes simple and informative models of DNA that can be built in only a few minutes. The nine models will illustrate many important physical properties of DNA including the major and minor grooves, antiparallel strands, right-handed and left-handed helices, positive and negative supercoiling, molecular flexibility, etc.
