Kinetic sand is a freaky-looking substance made of 98 percent sand and 2 percent silicone oil, so it sticks to itself, but won’t stick to anything else. It’s like an especially granular type of dough, and you can watch—and hear—the stuff in action in a new short “trigger” video from The ASMR Circus.

The ASMR Circus videos are part of a growing online community of people who get a pleasurable tingling sensation in the head, scalp, or back in response to certain auditory, visual, or tactile stimuli. The technical term is Autonomous Sensory Meridian Response (ASMR), and if you have it, chances are you’ll get the tingles from the soft crackling sound of the kinetic sand gently being prodded with a knitting needle. (Headphones recommended to pick up every nuanced crackle.)

Even if you don’t, it’s still oddly mesmerizing to watch the stuff seem to move all on its own:
