Of course not! Balloon bursts because the internal air pressure is higher than the external air pressure, but don't be scared by this air pressure (after all, it just blows out of your mouth). Because the air pressure is not high, the energy of the balloon is not high. During the explosion, the compressed gas runs to do work on the air, and the fragments will not have high speed and light weight ... In short, do you think it will hurt you to blow out a balloon fragment with your mouth?
