"More than a century before the Wright Brothers' first flight, humans were taking to the skies in hot air balloons. Today, with basic craft skills, you can build and safely launch your own balloons using inexpensive, readily available materials. Author and inventor Clive Catterall provides illustrated, step-by-step instructions for eight different homemade models, as well as the science and history behind them. Some, like the Solar Tetroon or the Giant Solar Sausage, are made from plastic bags and tape. Others, like the Khom Loi or the Kongming Lantern, are built using tissue paper and wire. THE HOT AIR BALLOON BOOK also shows readers how to heat the interior air that lifts these balloons, from tea candles to hair dryers, kitchen toasters to the sun's warming rays. Always keeping safety in mind, the author includes detailed guidelines on when and where open flames are appropriate, and the proper weather conditions to launch these lighter-than-air craft"-- Provided by publisher.
