“Earl Grey, hot!”

It was on Star Trek that Captain Picard would speak to the replicator and say “Earl Grey, hot!” and get a cup of tea.

Science Fiction, yes, but according to The Verge, NASA are building a 3D food printer. Sounds like a replicator to me.

They’ve started with printing chocolate, but are going to move onto pizza. I suspect that tea is much easier!
