<human>: How do you do this: How can you secure a wobbly shower head?

OPTIONS:
- Spray some expanding foam around the outside of the pipe coming out of the wall, it will add enough pressure to secure it.
- Spray some expanding foam around inside of the pipe coming out of the wall, it will add enough pressure to secure it.
