You must think before you drink. This classic wooden wine bottle puzzle will securely "lock" a wine bottle, or similar bottle such as olive oil, soda, large beer etc... into place such that it cannot be opened until you solve the puzzle brainteaser.
Its quite tricky. Best to try sober... But it does come with a very detailed instruction sheet on how to get the bottle both in and out of the trap. Note: You can use bottles of various heights, the string is easily adjusted to accommodate any bottle that will fit in the base.
