The Google Gravity effect uses JavaScript, HTML5, and CSS3 to create the interactive simulation. When you load the page, the script generates a 2D physics engine that simulates the behavior of the balls on the table. The engine takes into account factors like gravity, friction, and elasticity to create a realistic (or at least, seemingly realistic!) experience.

: A physics demo where numerous colorful balls fall into the browser window, which acts as a "pool".

: A variation of Google Gravity where elements float weightlessly rather than falling to the bottom.
