Subject: behavior of delete! method

I am confused by the use of the delete! method as applied to a string.
In IRB if I type

foo = "hello"
bar = foo
foo.delete!("h")

then both foo and bar become "ello".  How come bar isn't independent of
foo in this case?

If I then type

foo = foo + "oo"

then only foo becomes "ellooo" while bar remains "ello"

Why is bar independent of foo in the second case, but not the first?

Thanks,

Alex
