puts outputs strings, so it calls .to_s on its argument.

.to_s on a hash calls .to_s on all its keys and values, and mashes them together.

Use p @ec2.describe_instances, or require 'pp' and use pp.

p @ec2.describe_instances[2][:aws_status]

Now play around with (and read the docs on) Array and Hash!
