Add a pinch of sodium lauryl sulfate to the stannous chloride primer solution to help the solution get into contact with the plastic surface.

Holography Marketplace book -- lots of very practical information for making your own holograms, and good source of suppliers (though many are out-of-business now): https://www.amazon.com/Holography-Mar...

Countermeasures against hologram copying. Holograms are often used as a security seal, so making copies as shown in the video could be a problem without countermeasures: http://www.nli-ltd.com/publications/c...

I was planning to talk more about different types of holograms in technical detail, but I think I will save it for a future, dedicated video on making original holograms.
