Be Careful With Something "HOT"

Guys, if you think that the Tupperware is really cool because most of the promotion sales say it that way, now you've got to be very more careful if you use this product for "HOT" stuffs inside.
FOR EXAMPLE      : you are using a glass of Tupperware for hot water.
DON'T                    : shake the glass, even do it near your own body, seriously DON'T!!!
BECAUSE              : actually it is not safe to shake the hot water, and no one can give a guarantee (not even the one who have sold this to you) whether the glass will blow up in all of sudden or not.
FOR GOODNESS : use the Tupperware wisely, if you put hot stuffs inside, don't shake it, OKAY???
