ABSTRACT:
A kite includes a flat body portion which is formed from a thin sheet of a rigid lightweight material, such as styrofoam or balsa. The body portion may be formed in any desired shape which is symmetric about a vertical axis, such as a heart or a star. A slot is formed through the body portion and extends along a portion of such vertical axis. The slot is provided to releasably attach a forwardly extending keel portion to the body portion. The keel portion is formed from the same rigid lightweight material as the body portion. The keel portion includes a tab which is inserted through the slot to attach the keel portion to the body portion to form the kite. The keel portion further includes an aperture through which a string may be tied to the kite. One or more smaller slots may be formed through a lower region of the body portion to permit a tail to be secured to the kite.
