Einar fills the bird bath with foam
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Einar squirts dish soap into the bird bath in the garden, and spray water into it from a hose. He notes that you need a lot of soap, and not an excess of water, to make a lot of foam, and suggests that squirting soap into the small pool on the property would not work very well. He manages to create a decent amount of foam, which spills into the stony area of ground beneath the birdbath, but earns fourth place.
