Out, damn bug bite
Of all the devices you never even imagined existed but want as soon as you learned of its existence, this one ranks pretty high on the list. For about $13, Therapik is a cheap but useful device that instantly removes the itching from nearly any bug bite. It may look hokey (think Ed Wood sci-fi prop), but according to the tech blog Gizmodo, whose writers tested it and were surprised by its results, it really does work. You set the tip of the Therapik on your bug bite and press the button down for 30 seconds. Initially, the bite gets really hot. Then voilà, the itching is completely gone. According to the manufacturer, Therapik works on the principle that most insect bites are sensitive to heat, so by delivering an intense dose of heat to the bite, the venom is instantly neutralized. http://therapik.com.
