This is a smartphone case. A TPU smartphone case, to be exact. You've seen them before. We sell 'em at <insert shameless plug>

Tonight at CTIA in New Orleans, I spent a few minutes with Tech21, which makes cases like this out of orange goo.

What does that have to do with a rubber mallet, my knuckles and some old-school justice? Find out after the break.

Smartphone cases, orange goo, a hammer and a blogger's good hand


Ha! Phil if you really wanted a hand waxing there are places that specialize in that... Just saying!

We did this trick back in science class, all you have to do is mix corn starch with water and add food coloring gives you the same thing. I think mythbusters even messed with a mixture like this. Kinda like the cases though too bad my phone loves the nude wont let me cover it up.

Except thats not what this is? Its a proprietary gel substance that I can guarantee cornstarch+water cannot emulate. In fact the corn starch will "melt" off your hands and that did not happen here, and it also stuck to his hands, a characteristic much more similar to silly putty.

And we found the kid that was picking at the lead paint and eating it during class..
Corn starch melt your hands off you sir smoke crack. Here is a link on how to make a ooblek mixture You might want to turn your head they mix the water/corn starch mixture with their hands.

Take the time to watch the Mythbusters episode on this it is pretty good but Yes theirs is a proprietary mixture but so was that lead paint you ate as a kid.

This seems to be an elementary school child-like rebuke. If you were a little more interpretive you would realize that when he said "..'melt' off your hand," he clearly meant "melt off OF your hand."

Hook, line, sinker. :-)

I was just about to buy a regular TPU case from, but now I've canceled my order. ;)

But seriously, when will I be able to buy one of these orange good cases?

It seems that the goo itself is just the first step in the product, the thing he held up that kind of looked like a huge shoe sole is what goes into the cases. How the goo turns into that, I don't know.

You're a brave man, Phil. Risking your right hand? That takes guts, unless you are left-handed, then you played it safe but still cool nonetheless!
