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.
