No bottle opener? No problem. Just grab a butter knife from the kitchen and you can easily open a beer bottle (or anything else with a crown seal).
YouTuber Vegetashonor shows how to do it in the video above. Basically, you have to insert the knife under the edge of the cap and twist it outwards. Do that all around the edge to loosen. Then, holding the knife under the cap, bang it against a hard surface.
