Bottle
While the pear is small it is placed in the bottle, and the bottle is supported in the tree. Pear reaches full size in the bottle.
A full bottle of water
The bottle was full of liquid before it was frozen.
Freeze it first. Alternatively, fill it with oil so that when you knock it over it won't be water that you spill.

An empty bottle has less mass than a full bottle. This means that the empty bottle has less force to overcome when lifted which corresponds to less work to lift it.
The bucket is full of water and may spill. David's mind is full of strange thoughts. Draw a full circle on the floor, then jump into the center.
err, yes, because: bottle mass + soda mass > bottle mass
$20-$50 for empty bottle, $50 - $100 for full bottle
