Last week, we joined forces with our colleagues at WNYC's science podcast for kids "Terrestrials" to explore a unique geographic feature in Central Park called a recursive island, or an island inside of an island.

"Terrestrials" producer Alan Goffinski spoke to us from a rowboat in the Central Park lake as he floated near the unnamed island, and gave us one idea as to what the island should be called. Listeners responded with plenty ideas of their own.
