Hot Air Balloon Book
Angleščina
22 b
With detailed, step-by-step instructions, this richly illustrated science project book shows how to construct and safely launch homemade balloons. Some designs, including the Solar Tetroon or the Giant Solar Sausage, are made from garbage bags and tape, while others, such as the Khom Loi, are created from tissue paper and wire; yet all of the projects use inexpensive, readily available materials and are easy to construct with only basic crafting skills. Ever safety conscious, this manual provides detailed guidelines for various methods to heat the interior air that lifts the balloons, including when and where open flames are appropriate, and the proper weather conditions to launch these creations. With a full chapter on troubleshooting, should a design fail to fly, this book will make balloon engineers of just about anyone.
