2. Inflate the balloon in strict accordance to balloon manufacturer's
correct inflation instructions. Do not leave the balloon filling
shed while inflating.
3. Close the gas valve.
WARNING
Take extreme caution when handling the inflated balloon!
4. Tightly secure the neck of the balloon with a string before
removing the balloon from the gas nozzle.
5. Fold the neck over double and secure firmly. Tie the string
higher up to ensure the unwinder can easily fit. Note that the
unwinder hook must come out the other side, as shown in Figure
2 below.

Figure 2 Attaching the Balloon
NOTE
Be careful to attach the balloon correctly. This is the only correct
method to attach the balloon to unwinder.
The purpose of the unwinder is to unwind the suspension string
gently and slowly. For this to be possible, the unwinder must be
attached firmly to prevent its movement relative to the balloon.
If the unwinder were allowed to move about freely, the
suspension string would unwind too quickly and the radiosonde
might hit the ground upon launch.
