I love ice hockey, it is such a contact sport!
I don't know much about it - it looks incredibly exciting though! Is it very violent?
It is very physical with six people on the ice at one time.
Only six? Why is that?
There is a goaltender and then five players who skate on the ice.
Ah, ok. I've heard of the sin bin - is that where people go if they commit a foul? 
Yes, also known as the penalty box is where they go when they get a penalty.
