Spend ninety minutes in complete isolation, senses deprived and alone with your thoughts? Sean Corcoran of Float Sixty teaches us why it's a good idea. For our second On Site Shenanigans we head to Float Sixty in River North (Chicago) to learn about sensory deprivation tanks and experience them for ourselves. Also, Jim tries to bring his phone with him, and Hari learns what it means to "chill out".
