Firework sparks hurt relative to tea?
Question asked by: farooq
Asked on: 06 Sep 2009
A cup of tea is a large body of extremely hot water, essentially.
This means that it has an awful lot of energy, and cools quite slowly.
A tiny spark from a firework however has relatively small energy which it quickly loses - compare that to all the heat stored in the water molecules of a cup of water and you will see why the cup of tea will burn you so severely relative to the transient spark
Fireworks are very dangerous however so you should never go near them and take great care whilst using them
