Instructions: repair and upgrade my old pressure bag

⁣I overdid it and my 8 year old sack,
Needs repairs.
1. Check for leaks.
2. lay one on top of the other and glue again.
3. For even more pressure to inflate, he gets a 2nd layer from the outside.
4. Find more inflation critical spots and reinforce with tape.
5. The blur in the penultimate clip, that was my phone and not me.
6. pump up, sit on it and be happy when I lie in the sack and almost get crushed.
7. I know I'm different.
8. Any question or comment is welcome!
