Hello friend,
Your order is a digital download magic product,send via email. Please leave your email after payment. Sincerely Yours Levitation is the process by which an object is suspended against gravity, in a stable position, by a force without physical contact. This can be achieved through jets of gas pushing upwards against the object (as in air hockey), or pushing downwards from the object (as in helicopters, VTOL aircraft, and hovercraft). A sphere can be stably levitated in a stream of air without any type of control system, if conditions are right Customers who bought this product also purchased...
