This application allows the learner to experiment with fluid dynamics outside of the lab. Designed for the iPad, iPhone, or iPod Touch, the app creates a small universe in which the user can define physical constants such as viscosity, density, elasticity, gravity - and more. Learners can tilt and swirl their devise, change the variables, and see what happens. Compatible with iPhone 3GS, iPhone 4, iPod touch (3rd generation), iPod touch (4th generation), and iPad. Requires iOS 4.0 or later.
