CheerpJ versions of simulations run on most browsers on computers and tablets. You don't need to have Java installed! For compatibility with your device and browser, check this Google doc. Note: The HTML5 Gas Properties sim is more limited than the CheerpJ or Java sims.

Use the simulation movie version if you have trouble running the simulation.
