The kite experiment is a scientific experiment in which a kite with a pointed conductive wire attached to its apex is flown near thunder clouds to collect static ...
A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. [2] A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. [3]
The box kite was invented in 1893 by Lawrence Hargrave, [1] an English-born Australian, as part of his attempt to develop a manned flying machine. Hargrave linked several of his box kites ( Hargrave cells ) together, creating sufficient lift for him to fly some 16 ft (4.9 m) off the ground. [ 2 ]

The falling cat problem has elicited interest from scientists including George Gabriel Stokes, James Clerk Maxwell, and Étienne-Jules Marey.In a letter to his wife, Katherine Mary Clerk Maxwell, Maxwell wrote, "There is a tradition in Trinity that when I was here I discovered a method of throwing a cat so as not to light on its feet, and that I used to throw cats out of windows.
Drachen kite balloon, showing its characteristic shape. A kite balloon is a tethered balloon which is shaped to help make it stable in low and moderate winds and to increase its lift. It typically comprises a streamlined envelope with stabilising features and a harness or yoke connecting it to the main tether and a second harness connected to ...
A kite is a quadrilateral with reflection symmetry across one of its diagonals. Equivalently, it is a quadrilateral whose four sides can be grouped into two pairs of adjacent equal-length sides. [1] [7] A kite can be constructed from the centers and crossing points of any two intersecting circles. [8]
The delta-kites are growing in popularity since 2008 with around 12 companies offering delta-kites since 2008/2009. Between 2009 and 2013 kite technology has continued to grow. Kites have become lighter, more durable, much easier to launch and safer. Manufacturers have continued to add new safety features.
