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

Caswell nickel electroplating kit: https://www.caswellplating.com/electroplating-anodizing/nickel-plating-kits/nickel-electroplating-kit-1-5-gal.html (Price was already pretty high years ago, and has gone up a lot since; and the kit has fewer components than it used to. But it does work well.)

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-MarketPlace-6th-Franz-Ross/dp/0894960997

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/countermeasures.php

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.
