In his talk "I Leaped from the Stratosphere‚" Alan Eustace describes his experience of flying the stratosphere and falling back down to Earth. When his project to accomplish this first began‚ his question was if someone could linger in and explore the stratosphere. Usually‚ when the stratosphere was visited‚ it was by astronauts flying through it in a rocker. To accomplish his goal‚ Eustace contacted the Paragon Space Development program and asked if it was possible to have a human linger in the

has weight. It has molecules which are constantly moving. Air pressure is created by the molecules moving around. Moving air has a force that will lift kites and balloons up and down. Air is a mixture of different gases; oxygen‚ carbon dioxide and nitrogen. All things that fly need air. Air has power to push and pull on the birds‚ balloons‚ kites and planes. In 1640‚ Evangelista Torricelli discovered that air has weight. When experimenting with measuring mercury‚ he discovered that air put pressure

UNIVERSITY OF THE SOUTHERN CARIBBEAN DEPARTMENT OF CHEMICAL & PHYSICAL SCIENCES CHEMISTRY IN SOCIETY LAB (CHEM 107) LAB 2: THE AIR WE BREATHE Purpose/Aim To determine whether air occupies space and whether it can be moved and/ or removed. Introduction Air is a mixture of gases that composes the Earth’s atmosphere (NASA‚ 2015). Like all matter air has properties; one of which is weight‚ in each tiny air particle‚ there is a diminutive bit of weight. This weight is influenced by the pressure
