This method is easy, but be careful on what surface you’re using it—wood, painted surfaces, or some other countertops may scratch or get damaged by this method (my countertop’s survived okay, though). Just set the bottle cap on the top of the ledge, hold on tight, and bring your hand down hard on it. Sometimes it takes a few tries (as you can see in the video demonstration above), probably because it seems like the bottle’s just going to go flying and spill beer everywhere, but I surprisingly haven’t had that problem yet. It’s remarkably effective, and the best part is you barely need any other materials to do it. Of course, if you find yourself calling on this trick often, it might be time to invest in a cheap bottle opener. Just saying.
