Since its gun related I put it here.

My daughter is doing a heritage project and we got to talking about the war her grandfather fought in and I was telling her about the 21 gun salute that soldiers get when they die.

I was telling her the story of a friends father who died and one of the older gentlemen doing the 21 gun salutes had the shakes so bad, I later found out they use blanks. So my question is this, the flag we got from my dad is folded up with the bullet shells from the 21 gun salute. How does that work? Do blanks have shells?

Its a stupid question but my daughter wanted to know.
