<human>: Here is a goal: What can I use to make an old school walkie talkie?

How would you accomplish this goal?

OPTIONS:
- Attach two milk jugs with some string and stretch those apart to talk to someone else.
- Attach two soup cans with some string and stretch those apart to talk to someone else.
