The above video was taken though a telescope. The full details are at the link.
There are three components to the weather balloon setup, from top to bottom: Balloon, parachute, and instrument package.
Before you look at the video there are two things I wish to comment on:
When it explodes, the pieces are tiny. They look large because the video is taken through a telescope.
Second, the parachute properly deploys. Because of the angle of the telescope, right to left is down.
