Leslie Scott's Jenga Blocks

Origin
"Jenga" is a game that involves setting up small wodden rectangular blocks in a way so as to create a tower. The object of the game is to replace blocks from lower parts of the tower to the top without having the tower fall and be destroyed. This is one of the original sets that Leslie created, obtained from the V&A Museum of Childhood soon after its entry.

Effects
When the individual blocks are set up to create a tower, if it is inside a structure, the structure will mirror the integrity of the tower (i.e., if the tower topples, the structure will be destroyed. If the tower cannot be destroyed, the structure is nearly indestructible).

Trivia

 * The individual blocks are rendered inert of not used as a tower, so they are stored in a horizontal row in a glass box.
 * When they were collected and their properties discovered, it was suggested to be used as a way to make sure the Warehouse couldn't be damaged; however, due to the possibility of other artifacts interfering with the tower's integrity, this idea was declined.
