Balloon & CD Hovercraft

Over at Scientific American, they have simplified the hovercraft in to a fun project that can easily be completed in an afternoon. You might even have the materials lying around the house! Check out the materials list below and then hop on over to Scientific American for the step-by-step process to make your very own miniature balloon & CD hovercraft.

•     Pop-top lid from a plastic drinking bottle. (Reusable plastic drinking bottles sometimes use these kinds of lids.)
•     An old CD or DVD that can be made unusable
•     Craft glue or Super Glue
•     A medium-size balloon (should be able to inflate up to at least 28 centimeters, or 11 inches)
•     Stopwatch or timer
•     Large flat surface for testing the hovercraft
