User HurleyFX on Facebook, mentioned in the BTTF group:
"A friend and professional prop maker who has worked on films like Guardians of the Galaxy and The Imitation Game has decided to fix this by releasing a good replica of the drink; a 'Perfect' one, if you will. He also intends to donate a chunk of the proceeds towards Parkinson's Research, which I think is an amazing thing to do.Details are still being worked out, but the replica will cost around £30 each. These will be high quality bisphenol free HDPE reusable bottles with functional straw and sealed drinking nozzle and authentic decals with laser engraved best-before date of 21st October 2015 at the bottom. Knowing the standard of his work, they'll be something special.
Anyway, he'll need to get a minimum order of 1000 to place an order with his industrial contacts, so please pass this information along, and let me know if you or anyone you know would be interested. I'll post more details when I have them."
