Classic thermometers that use mercury or alcohol to take your temperature work great — if you're a sloth. Liquid only expands so fast, so for all you nurses who need to zip through a bunch of patients, Japanese company EJK has a new temperature-taker that'll accelerate your day. Its no-contact thermometer shoots infrared rays from twin emitters to take a person's temperature to within 0.2° Celsius in 3 seconds flat. So no more waiting — or giving fakers the chance to hold their thermometer up to light bulb. For around $213, you can retire your snail-pace under-the-tongue model forever.
