1. You can hang all sorts of things on a hot air balloon; a bed, your favorite recliner or a hammock! And you don’t need a periscope to look around.

2. Submarines are scary. Literally my worst nightmare to be in a metal tube under millions of gallons of water. Barf.

3. I can swim and dive without a submarine but I can’t fly without a hot air balloon

4. My punctuality is not GREAT, but...having a Hot Air balloon can help get me to where I want to go, and it won't matter that I'm late, anymore! I'm arriving in a hot air balloon. ;-)

5. I learned at Disneyland that I do not want to be stuck in a submarine for an extended period.  Even a Finding Nemo themed one...

1. best of both worlds: you can come up for air whenever you want, and you can sneak around exploring the ocean.

2. Crushed by a kraken sounds like a cooler way to die than hot air balloon crash.

3. I have two options for you.

a) a vehicle that you have control over where you can go. This vehicle is also able to be sneaky. This vehicle can also see currently unexplored depths.

b) stupid floaty boy that depends on the wind to go places, and also is made of wicker and fire.

What would you choose? Obviously I'm taking my sneaky submarine.

4. Given the fact that the ocean levels are rising, it seems like a smart long-term investment.
