Fireworks....Taylorsville Dayz

Recently the kids and I spent an evening watching the Fireworks with my folks.  We sat on the church lawn close to their house and had a great show. (they were even better than Murray Park on the 3rd)  Jr was very facinated with them this year (instead of being scared like every other year).  Katie just kept asking a MILLION questions like all kids her age I'm sure
- Why is that one red?
- How come that one is bigger than the others?
- Why does that one sparkle like that?
and on and on.........
