How do they get coke into cans?
Discussion
Filling cans
Cans are filled before the top is crimped on. The key engineering issue is that can walls are about 90 micrometers thick[citation needed], so empty cans are light, weak, and easy to damage. The filling and sealing operations need to be extremely fast and precise. The filling head centers the can using gas pressure, purges the air, and lets the beverage flow down the sides of the can. The lid is placed on the can, then crimped in two operations. A seaming head engages the lid from above while a seaming roller to the side curls the edge of the lid around the edge of the can body. The head and roller spin the can in a complete circle to seal all the way around. Then a pressure roller with a different profile drives the two edges together under pressure to make a gas-tight seal. Filled cans usually have pressurized gas inside, which makes them stiff enough for easy handling.
A few more mins googling would have helped me there wouldnt it.

They freeze a block of coke, frozen exactly in the same of the inside of a can of coke. Then, they roll this block of frozen coke in a vat of liquid aluminium. They have to do it quickly, otherwise the coke melts. Anyway, once rolled, they get it out and let it cool. They then heat it to above the temperature of liquid coke, but below that of liquid aluminium so the coke turns liquid. They then push a hole in the top and add a ring pull. Just before they seal it, they squirt a shed load of soda-stream gas into the top and then quickly close the top.
Et voila - a can of coke
(this may, or may not, be true)

If I don't find something using Google, rule of thumb is someone's taken a video of it !

Cadbury experimented with freezing the fillings of Creme Eggs to ensure it went into the egg and didn't mess up the outside. I regret to say the bloke who was telling me this, during the factory extension of the Trebor Bassett factory in Sheffield, was called away before I found out if that is what they actually do in production.So, bit of a non-story there. Interesting though.

I like that explanation and will store it in my memory regardless of what the truth may reveal. Et voila - a can of coke

Are you still in touch with him? I'm sure the readers would appreciate if you could finish the story off for us.
Good plan. I'll see what I can find out.Did you indulge in Toffee Popcorn in the end, by the way? If so, how did the Toffee Popcorn and beer mouthwash experiment go?
