bare skin and hot playground equipment can lead to serious burns. on five days this summer using in infrared thermometer at the hottest time of day, "gma" investigates tested equipment across the country recording the this metal surface in l.a., 129 degrees. this baby swing in houston, 130 degrees. this swing in phoenix, 150. at 140 degrees it can take 3 seconds for a child to get a second-degree burn, and 5 second to get a third-degree burn. if you think the temperature outside has to be sweltering for playground equipment to heat up. think again. when kara sinclair took her kids to the indianapolis zoo in early spring it never crossed her mind to check the temperature of the equipment. her then 22-month-old girl, tinley headed straight for the slide. >> she scooted forward as she scooted forward, it was, she stuck. she screamed really loud. something i had never heard before in my life.
