The context of this discussion was "hydrogen balloons" so that is the same scenario literally.

  You put it in balloons in science class, and not in a test tube?

    Yup. Chemical reaction to create hydrogen and had it fill a balloon over lunch. One of the other students got to explode it with a match taped to a meter stick. I could feel the air rushing by when it exploded. It was also quite loud but no big fire ball or anything.

      Your high school was way better than mine.
