File under good ideas:
this Pitcher with Insert
from Crate & Barrel has a column inside that can be filled with ice to keep your drinks frosty cold without the quick dilution of melting ice. You can fill with any of your favorite cold drinks
and lounge outside while it stays cold.
It's glass and it holds a generous 61 ounces - almost two liters. It's $8.95 online and at Crate & Barrel stores.
