Reaction - Acid and Metal | ThinkTac

Acids react with most metals to form salt and hydrogen gas. In this TACtivity, we react magnesium with citric acid to liberate some hydrogen gas. Inflate a balloon with the hydrogen gas and enjoy seeing the balloon float in air. Add a cotton thread to the bottom of the balloon and play around with the length of the thread to see the balloon go up and down.
