Has anyone tried this?
Materials
1 jumbo space bag(can be substituted for a garbage bag large enough to fit you)
duct tape
Vacuum
First get into the space bag.
Then zip it up as much as possible
Use dict tape to seal off the top where your neck is.
Ge into a comfortable position.
Have a friend vacuum out the air from the bag.
Now you can't move.
If the sea isn't complete, you may have to leave the vacuum on.
What do you think?
