I’d be careful, cause the popsicle molds will become quite brittle. You’ll have to use silicone and let them temper back to normal after you make them.

Also any technique suggestions would be helpful I was planning on making the mixtures and then pouring them into Popsicle molds (plastic?) And then submersing the molds in the LN. Has anyone else done anything like this?

The best containers are the study styrofoam shipping cubes that are used to ship tings in dry ice. Find one with roughly the volume you want then make sure it is protected by a sturdy, close fitting, cardboard box. Plastic coolers can crack (although I’ve done it many times) and the disposable styro coolers from the supermarket break too easily.

If you live in a big city it will probably be a PITA. If you live in a suburban or rural area, you might be able to convince the local welding shop to sell you some in a non-approved dewar.

I just want a small amount for making a few batches of ice cream with some friends for one afternoon and don’t want to deal with big 100L+ dewars. Is that viable? Or do vendors not deal with small amounts?

I would like to give you a device for easier handling of ln2. Please check your gmail for a message titled, “liquid nitrogen”

I am really excited about starting to work with the substance, but won’t be able to get a dewar. They are just too expensive. I called the welding supply and asked for suggestions. They said they have people come in with plastic coolers (although they did point out that the interior plastic does crack), animal semen containers and dewars.

Given my situation and the fact that I won’t need a lot of liquid nitrogen at a time (cooking for 2) do you have a suggestion on what to use? It seems a small plastic cooler would be the least expensive option, but seems like it might not be safe? Do you have any thoughts or alternative suggestions?

They are only pressurized to about 22 psi. The outlet is capped with a “phase transition device” (really a sintered bronze muffler). We use it all the time in front of people. Now… cracking the valve on an 800 psi CO2 tank is another story.
