Hello everyone its me again, translating for tmdrak. He has more questions, and here they are. Hey friends, I have a question. How would you store gases? Glass Tubes? If so how would you mix them without letting the go into the air. And I learned in class that if you want to combine gases you need to light it or something..how is this done? My main question is how would you combine gases and light them without letting them escape... thanks
