Do Bio balloons burst when helium is inserted into them?
When inflating a balloon, the balloon will take on its shape and begin to slowly float. That signals that there is a sufficient amount of helium in the balloon. If too much helium is inserted into the balloon, part of the balloon will abnormally expand and a short puffing sound will be heard meaning that the balloon has been ruptured. Unlike with conventional rubber balloons, a pop sound will not be heard. Ruptured balloons will not float, so please dispose of them properly.
