All the pictures of this “Tin Can Robot” show that it is made of an aluminum can, not a tin can…
Tin can rolls off the tongue easier.
Maybe it’s a UK thing or something those in EU think we use but actually don’t any more… last person to call an aluminum can a “tin can” that I knew of was my Grandpa because when he started drinking beer it actually did still come in tin cans… but he died a few years back and was in his 90’s.
“Tin can” is still whooping “aluminum can” in literature.
