This can be done whit a little praktice.I´we done it many times and it´s so cool
1 you put one of the balloons into the other You need to lupe whit pjur cult or simular.
2 you take some heavy furniture and place around where you will stand so you are supported.
3 you inflate the balloon to full size to stretch it
4 you lupe the inside of the neck whit pjur cult or simular
5 now comes the hard part first you put both your feet into the balloon and carefully pull the neck as far up you can then sit on your knees and slowly work the neck of the balloon up to your stomach
6 now start inflaing
7 as the balloon gets bigger stand in the center and as it gets bigger it will lift you inside the balloon
Is there anyway you could visualize this process? It would help my understanding in attempting this, as it sounds fairly complicated.
