Magic Mug

By: Muhammad Shutalim

Almost everyone who reads this post knows what mug is. According to wikipedia A mug is a sturdily built type of cup often used for drinking hot beverages, such as coffee, tea or hot chocolate.  but do you realize that some of mugs can do a little magic. Hahaha maybe only mug made in Hongkong can do that. Yeah but, seriously there are unique mug which are able to change its cover. For making it clear let’s see this picture bellow

This mug changes its cover when someone pours water into it. When it is empty the cover will show OFF word but when you pour the hot water or hot coffee, it’s gonna show you ON word. It is unique one, isn’t it?. Besides “turn on off mug”, still there is rare mug picture like this one (look the picture below). I am sure that person who made it is some kind of person who cares about environment. Why? You can tell by looking this mug. It will show you the effect of global warming when you pour into it hot water. He he

btw how come that picture change?. Actually some of materials for making mug are using Thermochroism. Thermochromism is the property of substances to change color due to a change in temperature.

You know buddies that first mug is made by using skeleton (annehira). Arkeolog believe that mug has been made firstly at stone age. But when I was searching on Wikipedia, it explains that mug has been made in china between 6,500 and 3000 BCE using potter's wheel.

That all my post for now, sorry if it is not really interesting but I hope you like it as good information thanks  buddy n_n.
