While it is still inverted, immediately light the gas in the second test tub e with a match. The dilute hydrochloric acid started to bubble with the piece of magnesium metal in it. We tipped it upside down than back and then lit a match and it goes POP! <span style="font-family: 'Times New Roman','serif'; font-size: 120%; line-height: 115%;">
