Hi,
Kinetic sand has extremely high viscosity, as it is more of a solid than a liquid. Such high viscosity values generally cannot be simulated in realtime as they require really small time steps.
There's extensions to particle-based methods that enable somewhat fast high-viscosity fluids, but still they're way too expensive for realtime use:

So the takeaway message is: this cannot be done in realtime, not with Obi, not with any physics simulator I've ever heard of. Even offline simulations typically take several minutes per frame.
