By the leaves of the trees, we will know the weather.
Get rid of that boring thermometer. If you want to tell the temperature using something that looks cool and quirky, you need the Hideyuki Kumagai Leaf Thermometer Paper. As the name indicates, this thermometer paper is shaped like a beautiful green leaf, but changes color according to the temperature. During cold days, it turns into a charred brown color while on really hot days it will turn yellow. Stick the leaf on your door or wall for an easy to spot thermal indicator.
