Is this science or logic?

Science... you're pouring hot boiling water (212F) into a room temperature mug. That's a least 140F temperature difference. Cold water (about 40 F) gives a temperature difference of about 30F. When you have a great temperature difference, the mug doesn't expand quick enough or evenly (bottom is hot while the top is cold) so it cracks.
If you take a cold mug with water, heat it in a microwave, the mug is warms up with the water so the expansion is even, resulting in NO cracking.

i remeber i learned this in science..i dont really remember that much but its a chain reaction...when something is hot..thing start breaking down easier because the hot water reacts more than cold water..aghhh i cant explain it that good i frogot how it goes.

science
its to do with the heat. heat causes things to expand and contract and this happens with the teabag when the hot water is poured onto it.

I have never found this to happen. Maybe it happens because of the steam that hot water gives off.

The air is searing to escape from the bag perhaps.. I've noticed too..

Because heat causes expansion.
Good Luck!!!
