Grobag egg
The Grobag Egg shows you the temperature in easy to "read" colours. Blue if it's cold, yellow and orange if it's somewhere inbetween, and red if the roof is on fire.However, this Grobag Egg is supposed to be placed inside nurseries, so that you can easily determine how hot or cold a baby's bed is and adjust accordingly.
