Wow that beats the heck out of disconnecting the joints, rolling it out by hand, and then soldering everything back together. That would have saved me hours in high school. Plus, magnets.
Funny trivia: The article uses ' as delimiter here, as in 10'000 although Germany (the domain name uses .DE and the company is based there) uses the . here -> 10.000 Seems like the author ('from Italy') of that post is using the swiss notation? Any other (european) country using ' as a thousand separator?
We certainly didn't try to unroll them, however, and I let my mentor solder them back together.
