Описание: The "paper smoke glass science" experiments demonstrate air pressure, density, and convection: rolling and burning paper inside a glass makes the smoke settle at the bottom (no fresh air, smoke cools and sinks), while a "smoke waterfall" uses a rolled paper tube angled downwards to cool smoke, causing it to sink and pour like a liquid due to density differences, even appearing to flow upwards if placed right. This showcases that smoke (hot air + particles) rises because it's hot and less dense, but when cooled or confined, it sinks.
