Imagine an apocalyptic scenario: if your house is full of canned food, you are well prepared for disaster – but your can opener doesn’t work! What would you do? Fortunately, we know that it is a very unlikely situation. But let’s look at this trick – it’s so convenient that even Bear Grylls uses it!
Everyone knows the trick to take off a beer cap without a bottle opener, right? How about opening a wine bottle with a key instead of a bottle opener?
