Shockwave Player not Working?
The Shockwave Player plug-in cannot be installed on mobile phones, tablets such as the iPad, and Chromebooks. Don't worry ... we have you covered. For a similar experience, try the HTML5 Interactive titled Standing Wave Maker at the Physics Interactives section of our website. You'll find it works quite well on all devices.
