Product placement
Meadowhall: This is a shopping centre where the products were purchased. It merely appears, and removing it would not change what happens in the video.
Squishies: These are the products being shown and interacted with. They are toys designed to be squeezed. They ACT, as their interface (squeezing) is operated and a visible result (squishing) comes from them. Removing them would change what happens in the video.
