Kinetic Sand
At the STEAM Café and discovery centre in Paignton, they have a unit that can use an Xbox Kinect unit to scan a surface and map this on a screen. To use this, the café wants to use Kinetic sand rather than play sand.
The idea is that the sand is in the try at the bottom and users can contour the sand, building, hills, valleys, mountains etc, which can be scanned and displayed on the built-in screen. The Unit also has some other games and activities built in that are designed to be interactive.
As we need something like 200kg of this sand, it works out expensive. As with most things, it can be made, so I have been looking at one solution to this.
However, this recipe uses material that is based on food, so could go mouldy over time, there is a silicone oil based version of this which we are looking in to.
I undertook another ddg search for kinetic sand and silicone oil and found this which appears to be using olive oil, which I don't think is silicone based anyway.
I will ask about this on Science forums once I have some ideas and or links to evidence prior research to asking.
