The human mouth, which maintains a near-boiling temperature, needs to be constantly cooled by liquid-nitrogen pills or a jaw-mounted mouth fan. Take a more delicious route to cooling your maw with today's Groupon: for $5, you get $10 worth of water ice, custard, and gelata at Zeppe's Italian Water Ice. Today's deal is valid at Zeppe's Logan store, located in Providence.

The arctic artisans at Zeppe's Italian Water Ice concoct an innovative menu of frozen delights to satisfy even the most persnickety of sweet teeth. Cool down palates with a refreshing italian water ice—a fresh-fruit purée with the rich consistency of ice cream minus the fat, cholesterol, dairy, and incessant mobile jingle. The innovative treat comes in 25 rotating flavors (with 10 on the menu each day), including strawberry lemonade, root beer, and coconut crème ($1.59 for a kids' size, $2.29 for a regular, and $2.85 for a large). The creative menu also features old-fashioned custard, an egg-based, creamy mouth-pleaser, which showcases its rich, smooth texture in chocolate-lovers' chocolate, pure vanilla, or twist ($2.19 for a kids' size, $3.19 for a regular, $3.89 for a large).

For those who don't want to play favorites, Zeppe's offers gelata, a perfect mix of water ice bundled between layers of old-fashioned custard. Zeppe's recommends a mélange of coconut-crème italian water ice and chocolate custard to create an Almond Joy–esque frozen dessert, although any combo of the daily flavors can be used ($3.39 for a regular, $3.89 for a large). For a more portable nosh to take to the park or an awkward family reunion, opt for the gelata shake ($3.99 for a regular, $4.49 for a large).
