2010年5月13日 · For the pop method, you need to position a small test tube upside-down over the reaction producing the hydrogen. Since hydrogen is lighter than air, it will collect in the test tube. Next, light a match and tilt the test tube slightly and you should burn the hydrogen and hear a small popping noise kind of like a cork being shot out of a cork gun.
