Now a couple my students made. Sorry they are not on Youtube so its links. They are both about balloons and have a few small errors. The first at least is visually impressive. We got a weather ballon and filled it with air. At this point it has a mass of 3kg but almost no weight (Ok it has a weight of about 30N but almost all supported by bouyancy). Any way you can throw it at people and knock them over
