Whats this??

Seen this one one of the gardening shows I was watching but they didnt say what it was, anyone know?

Apart from the obvious (being a cardboard box) as the oh said

It's a cardboard box containing a live colony of bumblebees, which can be purchased from various suppliers. You either leave the box as it is, or place it, complete, inside a wooden "hive".
Have a look at this thread for some more pictures.
