Q: Why do my Floating Tip Jars sink into the ground instead of float?

There are two reasons why this may be happening:

1. You cannot take a Floating Tip Jar to your Inventory while it is floating. It should only be taken to Inventory while it is not in use. You can rez a new one from original box and start over if this is the case.

2. Your sim must have "Collisions and Physics Enabled."

This can be done through the "Region/Estate" window. Only the sim owner or assigned "Estate Managers" have the ability to change the settings for the Estate.
