last week i was making a cup of hot coffee for my mum, and she usually drinks it super hot (i.e. no cold water added), so after the water boiled I happily poured the boiling water into the cup. To my dismay, there was a loud *crack* and the coffee level in the cup started falling rapidly, while the size of the puddle on the floor expanded.
I was kinda shocked by this suddenly happening since i've always poured hot water into cups without incident. So I was just staring at the coffee leak out...It was leaking out rather than bursting out all at once because the cup had a hairline crack in the middle, but the 2 halves were still joined together. Anyway, when there was about 1/3 liquid left in the cup, I finally came to my senses and placed the cup in the sink. wasted all the coffee..I had to make a fresh cup.
I discarded the cup of course..but a few days ago, my mum took out a new cup to replace the broken one, and it was the same type as the one before. Some free cup from some event some time ago. (lol I can't really remember..I think it was some CC event) When she poured the hot water into this cup, guess what happened? The cup cracked again! lol...so poor quality. But I had already warned her beforehand that since that incident last week, we should be careful not to fill up a cup with hot water while holding it. In other words, make sure you don't touch it, in case it cracks then won't get scalded. Luckily I wasn't holding the cup when mine cracked.
So luckily she wasn't holding it either, and since she had prior knowledge of such a thing happening,she quickly took another cup and poured the drink into it, thus avoiding wastage. haha quite quick reaction..Normally a cup wouldn't break unless there's a huge difference in temperature btw the liquid being poured in and the cup itself, so i dunno what happened. Maybe the cup just wasn't made properly? those with thicker walls are also more prone to cracking when hot water is poured in, but all my cups a home are about the same thickness, and we've been using them for years with no problems.
And this also reminds me of the time when someone's cup of milo exploded in the coffeeshop. Haha this one is really exploded, not just cracked. Er, but a small explosion la. Fortunately it was a cup of cold milo, not hot. It was in one of those beer mugs, and about 2 minutes after it was served to the customer, it suddenly broke into many pieces, and milo shot out everywhere. But most of the milo leaked out over the table and floor...I think the customer in question was quick enough to move away from the table, so she wasn't drenched in milo. But she obviously complained..and got a new cup. lol..but the coffeeshop staff, and everyone around tt table were kinda shocked..
