This short guide has been written to describe the basic principles for making your own fishing floats with a variety of readily available materials. Choice of materials and the basics of float construction are covered, including advice on glues and waterproofing. Patterns and construction notes are also included for making a selection of floats to cover a wide range of fishing situations.

Geomembranes are flexible polymeric sheets which are used as relatively impermeable liners to contain liquid and vapour. With uses ranging from canal liners to hazard waste landfills, they are used extensively in a range of industries such as water conservation, mining, construction and waste management. A Guide to Polymeric Geomembranes: A Practical Approach offers an informed overview of the developments in this field and includes: Detailed discussion of the major geomembrane types Manufacturing methods Key performance properties Industrial applications Testing and chemical resistance of geomembranes Failure analysis methodology Written by a polymer research specialist with more than fifteen years experience in industry, this practical handbook covers the manufacture, use, installation, durability, lifespan and performance of geomembranes. It covers all the information required to enable the reader to select the most suitable geomembrane material for the job. This book is a useful reference for engineers and professionals in industry, environmental consultants, polymer and materials scientists, and government agencies and policy makers. It is of particular interest to those designing, commissioning and operating waste management sites, landfills, mine leachate ponds and water containment facilities.

A low priced book on a number of interesting knots, including how to replace the coverings on fishing floats, and a number of different ways to cover rails, knife handles, and anything that stays still long enough to cover. Care has been taken not to repeat the knots already shown in the companion volume KNOTS, USEFUL AND ORNAMENTAL, so there is a lot of new material in this book (though, for the benefit of those who only want this one book, there is also a section on the most popular knots)

A summary of projects about making things float and sink.

An estimated 4.1 million people in the United States participate in recreational sailing. Yet the large library of sailing literature leaves many of them high and dry. On one side are technical guides for America’s Cup boat-builders; on the other, simplistic books for weekend sailors with little interest in science. In Float Your Boat! professional and amateur boaters alike will find intelligent and understandable answers to such questions as: What were the key innovations that made sailboats more efficient? How do you increase the speed of a boat? How do sailboats travel into the wind? Why are so many explanations of sailing so wrong? Sailing enthusiast and physicist Mark Denny first traces the evolution of the sailing craft, from prehistoric coracles made of animal skins and antlers to the sailboat’s reinvention as a pleasure craft during the Industrial Revolution. He then identifies specific sailing phenomena—how wind drives modern Bermuda sloops, how torque determines stability, why hull speed exists—and provides the key physics principles behind them. Whether you are an inquisitive landlubber who has never set foot in a boat, a casual weekend sailor, or an old salt who lives for the sea, Float Your Boat! is an accessible guide to the physics of sailing.
