I was born in Australia but grew up in England <a href=" http://www.portula.eu/essay-about-writing.pptx#physician ">i want to be an entrepreneur essay</a> You can open a bottle of beer with anything. The concept is simple — we need to somehow MacGyver a lever, class one. The cool thing is it's one of the oldest concepts in physics, and you can basically make one from kind of anything. Spoons are the dream, lighters are the classic choice, flat rocks will do, iPhone cases work extremely well, or at least mine does, and, yes, Citibike keys can be pressed into service in a pinch. The emphasis overall is on Sturdy — whatever it is shouldn't have a lot of bend, or be too likely to deform or crack against the metal of the cap. No sporks, no foods (I don't think?), no actual phones, no many-different-things made of wood (if we're being safe), and, again, no actual phones.
