Cornflour tentacle monster

I've played with cornflour (corn starch) a few times, mostly when I was supposed to be mixing it up for cooking. It's strange stuff.

Here it's taken a few steps further (or tentacles further?) with cornflour vibrated at 80Hz.

There are a lot of these games with cornflour on YouTube, culminating in a swimming pool of the stuff, allowing people to actually run over the top of it. I think I'd like to try that.
