Soft Serve at Home?

Everybody like soft serve drippin’ down in the June sun
I tried to shoot a thought, ah but the thought sunk
Nothin’ to do but scratch words in the dirt and
Watch the water roll down

Logging this here for future reference; a technique from ChefSteps that uses dry ice in a stand mixer to make soft serve at home, which I was just explaining to Kiley wasn’t possible.
