The scene
Niebla Gallery · Packing roomThe exhibition’s favourite piece is a blue glass sphere that seems to hold a moon inside. This morning it vanished. During the shift change, three people left with a closed container.
The courier has already collected the parcels. The gallery kept photographs and measurements of the containers. Before stopping the right shipment, you must work out where the intact sphere could be travelling.
What we know for certain
One of these three people carried the whole sphere out inside their only container. There were no accomplices, extra containers or alterations. The sphere and containers are rigid. Measurements and observations are reliable; statements may be lies.

The piece is a solid sphere measuring nine centimetres in diameter. It cannot be folded, dismantled or compressed.
02Lucía’s box
Its internal width, depth and height are all eleven centimetres. Removing the lid leaves a square opening measuring eleven by eleven centimetres.
03Óscar’s case
It measures twenty by fourteen centimetres, but its internal height is only three centimetres. It is rigid and stayed closed without bulging.
04Mara’s jar
Its interior measures fifteen centimetres in diameter and twenty in height. However, its only opening is eight centimetres in diameter and cannot be widened.
05No other way out
Everyone left with their hands visible, no bags and just one container. None of the containers was broken or altered.
