Gravity depends largely on mass, the bigger the planet the greater the gravity should be
hot air rises... and if you add enough hot air you should be able to elevate various objects
Pilots first instrument used in flying was a compass so they could orient themselves in what direction they've been heading and should head based on time and speed.
The object is safe to touch, as it does not emit heat enough to harm the skin. The substances used to create this "glow in the dark" effect is generally toxic, and should not be consumed.

An object can float on water only if its density is less than water.(Archimedes principle). So, to make an object float, its density should be low. For this purpose, its mass should be less and volume should be greater(d=m/v), so to make heavy objects to float, their volume should be as less as possible.
