Why is the streamer useful when performing the the balloon rocket experiment?

Question

This is for my physics class. I think that it stabilizes the balloon when it propels it self in the air, but I am not sure.. Any thoughts?

Answer 1

If you assume that the balloon has a top and that it needs to go straight up or down the streamer could act as a stabilizing anchor, like a drag to hold it straight. Other wise maybe it's used for visibility.

Answer 2

Hi. Sounds right. Same as a tail on a kite.
