This film demonstrates a science experiment using dry ice to create a hovering disc. A hollow metal can filled with dry ice (solid carbon dioxide) is placed on a smooth glass surface. As the dry ice sublimates into gas, it escapes through a hole in the can, creating a cushion of gas beneath the disc. This gas film reduces friction, allowing the disc to hover and move with minimal force, as shown by its ability to glide effortlessly across the glass. The experiment highlights the principles of sublimation, gas pressure, and friction reduction.

Keywords: Dry ice, sublimation, carbon dioxide, gas, pressure, friction, hovering disc, science experiment, demonstration, low friction.
