Each project chapter in this book is split into two parts. The first part covers the design and science of the balloon. The second part contains the instructions for building.
You can build the balloons in any order you like; all of the instructions for a particular design should be contained within its own chapter. Start with an easy one, though—either the Basic Trash Bag Balloon (page 41) or the Kongming Lantern (page 71).
If you run into problems building these balloons, or if you cannot find the right materials, see the troubleshooting tips in chapter 11 (page 211). I have tried to gather all of the fixes and advice there.
All building and launching should be done under adult supervision. Many of the projects contain steps that use heat or sharp tools. If you have not used a particular tool before, ask someone to show you how to handle it safely. Wear appropriate safety equipment, especially heatproof gloves and safety glasses when handling containers of hot wax. Store your hot soldering iron in a proper stand when welding sheet plastic—don’t just lay it down.
Read through the whole of chapter 2 before you launch your first balloon. Follow the safety advice and remember that safety is your responsibility. If you do not follow instructions and warnings, the balloons in this book can cause injuries or damage. The author and publisher accept no responsibility for damage or loss caused by anyone following the projects in this book.
