One man has a unique vehicle for traveling around the Caribbean: A floating bubble.

Reza Baluchi attempted to travel from Florida to Bermuda in a similar device in 2014, when he was thwarted (or rescued, depending on how you look at it) by the U.S. Coast Guard.

Now, Baluchi is back, spending three nights on a Florida beach putting together his "hydro-pod" for a journey to Bermuda, Haiti, Cuba and Puerto Rico, all in the name of charity.

The hydro-pod looks like part Ferris wheel, part hamster ball.

The bubble run around the Caribbean is clearly ambitious — the distance from Florida to Bermuda is about 1,000 miles, or a 2.5-hour flight.

“Mind is power," Baluchi told NBC Miami. "It's 85% your mind."

Those familiar with the mentality of endurance runners likely won't find Baluchi's project surprising.

He says he is attempting to run across every country in the world in order to raise money for children. Among his other stated goals are promoting world peace and creating a reality television show.

When the Coast Guard picked him up in 2014, they reported finding Baluchi, in his bubble, "disoriented and asking for directions to Bermuda."

"They burst my bubble," said Baluchi. "Now I put signs up that say 'Please don't burst my bubble.'"

For the 2016 endeavor, Baluchi is packing protein bars, sea sick gum and Gatorade.
