OK now imagine a light shining directly down from above.  The square-down

devices reflect the light four ways, but the triangle-down devices reflect
it only two ways.  The signal return could be detected remotely, which would
indicate the range of h predominant in that sample.  If you run off to the
patent office with the idea, say nice things about me.

 

I'm late to this conversation,  so I'm going to be brief to catch up.

I had a nerf ball I tried to slice up but so far it was an epic fail.  It deforms under the blade so I haven’t been able to make a good clean cut.  I might try the old nichrome hot wire technique but I don’t have any nichrome.

If that turns out to be right, I will totally swoon.  Better yet, if it turns out to be right, we will be famous (but not rich, dammit.)  Reasoning: we publish a result like that, the science community will go totally nuts trying to explain why it works.

 

If anyone knows how to make a closed-foam polyvinyl that would work, I can get my buddy to 3D print us a mold.  Alternative: we can use that expand-o-foam stuff they sell down there at the hardware store, or perhaps bondo body putty.  Or we could make them out of balsa wood (that is the most isotropic wood I know of.)  Other ideas?
