I thought this was a pretty interesting video. It shows how Lush makes one of their bath bombs.[youtuber youtube=’http://www.youtube.com/watch?v=r9SItFK7Vp8′]
A few things are noteworthy.
1. The green color they get is actually from dyes and not the avocado.
2. I doubt they cut up avocados like this every time they make a batch
3. Hand packaging everything can take a lot of time.
Still, if you were every curious about making these types of products, this is really how it is done on a production level.
