Thames & Kosmos Structural Engineering: Bridges & Skyscrapers Ravensburger Just keep flipping the whole

Just keep flipping the whole thing over again and again to watch them go

This building set also has downloadable step-by-step instructions for two motorized builds

The blank slide can be used to view other objects at 8x magnification

Taking the SpinAgain apart so you can start spinning again might just be the best part

Thames & Kosmos Structural Engineering: Bridges & Skyscrapers Ravensburger Just keep flipping the wholeDo you ever wonder how bridges span huge distances and how skyscrapers stay standing? Structural engineers use physics and their knowledge of the properties of building materials and geometric shapes to design structures with sufficient strength and stability. With this kit of modular building pieces, you can learn the basics of structural engineering by conducting a series of 20 model building experiments. Each model demonstrates a basic principle of
