The YouTube channel Hyperspace Pirate[0] has been consistently uploading fantastic videos documenting their attempts to make their own homemade liquid nitrogen machine. They don't shy away from including all the technical details, and throw in plenty of hilarious deadpan humor too. Highly recommend them if you're interested in this topic.

Yep. Been watching for a while.

I really want affordable dip and dots at home, and to do some cryogenic experiments that are only possible using liquid nitrogen or liquid helium.

Also those Dewar's arnt cheap, nor are the pumps

I got a 10L dewar on amazon for something like $200 a couple years ago. Certainly has paid for itself in party entertainment.

FWIW, lots of these steel cups that are popular these days are vacuum flasks and cost practically nothing.

What do you do for party entertainment with it? Fog machine? Smoky cocktails?

LN2 ice cream is the big draw-- since you can make single servings of random flavors and the results are really good.

People enjoy playing with high temperature superconductors too.

Okay, now you absolutely must explain how you are employing high temperature superconductors at a party. :) I want to go to some of your parties! I have heard of the ice cream. I must try that perhaps some day...
