I believe they keep one end open to allow for the expansion. Here is a video, look around the 3:18 mark.Originally Posted by Kalle Mandelstam

Wow, really interesting! My next question was going to be why the ice doesn't shatter when bent but the soap in the water makes it pliable.. Always so cool to watch someone who is a master at their work, no matter what it is. Thanks for the link!
Yeah, that was a cool video -- I watched the whole thing
No problem, glad you enjoyed it. I love anything related to making things and it is impressive to watch talented people.
The question is whether it would freeze sufficiently at the 0 degrees typical of a home freezer rather than the -50 they mention in the video. But might be a fun experiment, since you don't need to make such a tight bend, might not need the ice to be as pliable.

Men hang out their signs indicative of their respective trades; shoe makers hang out a gigantic shoe; jewelers a monster watch, and the dentist hangs out a gold tooth; but up in the Mountains of New Hampshire, God Almighty has hung out a sign to show that there He makes men.

I'd like to try this too...but can you explain what the purpose of the sand is? Thanks
The sand prevents the tubing from collapsing as you bend it. Without the sand (or ice), you'd likely end up with a kink in the tubing, depending on how much bending you do.
I've had success bending light tubing with sand in it as well. A small trick is to put the sections in the oven at 350 for 10 minutes to warm them before setting into a jig. Makes them more pliable. Use leather gloves to handle them.
