Inside a crate on level 1, you find
A toy gyroscope. It functions exactly like a normal toy gyroscope, but when spun normally, has almost a million times the angular momentum it should for a half-kilo toy. It seemingly never stops spinning and is virtually impossible to tip over. You also find documents and blueprints in the crate indicating that the device was created for use in satellites, but was unusable because the momentum could not be overcome by any means known to man.
