Question: what would happen to the bollon after it had gone into space would it just flot back on down to erth or would it pop

Good question!! As the balloon goes higher in space it expands, because the air pressure is much less the higher you go. So eventually it becomes SO big that it pops.

Then the things that it’s carrying, like cameras and tracking equipment float down to earth on a parachute, and we go and collect them and see all the wonderful photos!
