You can't use bare variables inside a string.
x=7
puts "The number is x"

This will return (of course) print out "The number is x" because ruby has
no way of knowing that you actually wanted it to print out the value of
the variable x instead of a literal x. If you however put #{} around the x,
it will be substituted with the value of x.
That's the point of the #{}. There's however no point to pass a string to puts
that only contains a #{} because than you could as well just pass the variable
to puts.
