Tae Kwon Do Vest

Want to know just how deadly (or ineffective) your newly acquired tae kwon do kick is? Figure it out with the Tae Kwon Do Vest. This wearable project uses a bunch of piezoelectric sensors to measure the kick strength, translating that into a numerical figure for you to gloat over your opponents. I think it doesn’t really matter for the recipient as he/she will feel nothing but a world of pain instead.
