Unity tutorial _ Add teleporters and sounds

Having hit a lighting rabbit hole, I've put some questions to the Virtual Animation forum. Whilst that question is cooking, I've turned my attention to watching a webinar on Creating a VR environment and now the Unity tutorial, creating a teleporter and sound effects. This is how I want my viewer to move around the scene. This will hopefully avoid motion sickness and added sounds will create more immersion.

Tested and the teleporter worked. 

Next step included dragging an interactable object into the scene. In this case a green bubblegun. The test is to see if I can grab it. First try, I realised that I'd placed the teleport point too far away from the box. Headset off, move the teleporter and try again...

It worked!

Next step....add a sound effect

Adding contact sound to an object
