PERU: Deep in the Amazon there is a river… that actually boils. You can fill an empty mug with a teabag and have instant hot tea. Animals that fall in are instantly boiled. The average coffee is 130*F; this river has been measured at 210*F. Yikes! It is an awesome thing to behold- just don’t get too close. For more information, check out the videos below. Students boiled water in class, measured the temperature with a glass thermometer, and then converted the degrees from Celsius to Fahrenheit.
