It is not so much high temperature as temperature gradient - a change in the temperature from one altitude to another - and the resulting density changes this creates. The different layers act like lenses and make the light move in different ways at different times, giving that sparkly effect.

If the balloon accelerates (changes its speed), then that means that forces act on it. If any object "does not follow" Newton's First Law, that means that the conditions are not fulfilled - the conditions being that no net force acts on an object.
Because as what we know exsiccation is the act of drying out and the deprival of a crystalline substance of its water of crystallization. So, if you store it on a high temperature, moisture will form. #kgod.
They re- act normally and keep swimming, though some creatures get pulled away.
Bouyancy, pressure, and gravity.
upthrust and gravity
wind resistance, gravitational force, friction.
Prepare the balloon by placing scotch tape on opposite sides. You can push the skewer through without it popping but you need to pop the balloon soon after pulling the skewer out because it will loose air. You can make that part of the act--to demonstrate that it is a real balloon and to "hide the evidence".

"Altitude" is a synonym for elevation, or for the act of elevating, "ascent" (verb form, to ascend).
There are multiple forces which act on an aircraft, Lift, Gravity, Thrust and Drag, all would come into account when an aircraft is at altitude. If you wanted to get more specific, you could say gravity and lift control the vertical movement of an aircraft, but are not attainable without thrust.
Launching is the act of sending a vessel into space. These days, it is usually done by lighting a rocket to carry the craft from ground to orbit, but sometimes they get to orbit via a smaller rocket launched from a high-altitude aircraft.

It has lift by having hot air, which rises. Gravity, Lift, and Friction act upon the balloon hovercraft. The friction is a fluid friction known as Air Resistance.
When the air is heater, the molecules move faster and expand to fill the volume of the container.
