Awesome Pain

Piano? More like paino. Mattias Krantz has a thing for making dangerous musical instruments. After creating a piano that’s capable of electrocution, he moved on to one that triggers paintball guns when its keys are pressed. It plays music by turning its victims’ screams into notes.

The iTENS device is like having a personal trigger point therapist: this small yet mighty portable device buzzes tiny electrical signals through the skin to intercept pain, helps release endorphins and works via your smartphone. So proceed with confidence, weekend warriors.
