A new twist on hot air balloons!
Give your students a lesson on geometry and measurement while they build hot air balloons based on geodesic domes. The Geodesic Hot Air Balloon Challenge includes plans and instructions for several different models ranging from fourteen inches to over five feet tall, all from standard size tissue paper.
The bigger the balloon, the better it flies (providing a good lesson on surface area and volume)!
Flat panels made up of pentagons and hexagons are easy to assemble and repair. These balloons can be launched with an electric hot plate (great for flying in a gymnasium), or sterno solid fuel (outdoor use only).
Thoroughly illustrated instruction manual includes information on the history of hot air balloons, plus tips to make construction easy.
The Geodesic Hot Air Balloon Challenge Package includes: Launcher, Hot Plate and balloon Starter Pack with metal wire, tissue paper in assorted colors and glue. Balloon Packs and Single Balloon Kits include: colored tissue paper, metal wire, and glue.
The challenge requires four gel heat cartridges for outdoor use (see below). Appropriate for grades 6 through 12. The Sterno burns for approximately 4 hours.
