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.

I bought one of these last month and I absolutely love it!
I have one of these, but I melted the insert when I put a Hot tea that I wanted it iced. oops. just a heads up
Ooh, I have one of those! Although I really only use the insert when I have people over. Otherwise I just make myself a big pitcher of iced tea and keep it in the fridge.
It's great though.
