Progress does not stand still, and now you can see many things differently. Those that were previously invisible.
Drying hair dryer. This is much more than drying ...
Waves around a person in the cabin.
Jet invisible gas.
Shot from a Kalashnikov AK-47.
Gas cloud when fired from a revolver.
An explosion of fireworks.
Invisible world around burning candle.
Walk on water insect.
