flink July 1, 2014 11:26 AM But sliding the object beneath a cavity in a brick accomplishes the same feat.I fail to see anything special ability, here. Noel K Frothingham July 1, 2014 09:17 PM Where's the cavity, flink? OrangePanda July 2, 2014 05:26 AM I agree with Flink, plus the moment you actually put pressure on the top rather than simple touching it surely you'd put the shape of whatever you applied pressure with. So if they were pushing that block with their finger then it would compress and they would feel the cylinder. flink July 2, 2014 07:58 AM @Noel K FrothinghamThe cavity is in the hypothetical brick.That little bit of material hides the object underneath it from touch. But so would a brick in a similar configuration. Joe Sobotka July 2, 2014 12:18 PM Ya,,, maybe I'm missing something, but I don't get it. Its the same thing as putting a thick piece of foam on top of an object.

Mass produce Jaesun_1 July 2, 2014 08:36 PM Sounds like something James Bond could use with some imagination. Vlad Tepesblog July 3, 2014 12:26 AM At last! We finally have the ability to hide things from blind people! Tom James July 3, 2014 08:07 AM This amazing invention is 1 step below Warp drive. Vulcan's will be arriving soon for First Contact. Magnetron July 5, 2014 05:38 PM Fab idea! The possibilities are boundless....I'm currently using the same sort of technology to cloak the spring/frame assembly which cut into me on my favourite chair. My matress is just a load of old rusty springs which are terribly uncomfortable too. I'm gonna cash in on this before it catches on!
