Give this video a thumbs up if you enjoyed the calm flight as i have. 45 grams is the flying weigh of this micro discus launch glider, light enough to rise and stay afloat on this fine spring day. As the air in contact at the earth’s surface warms, the amount of motion or vibration of the gases of the atmosphere (nitrogen, oxygen and argon atoms along with molecules of carbon dioxide and water vapor) increases. This in turn, produces a greater amount of space between the atoms and molecules making the air less dense which causes it to rise.
