Jeff Potter did this at Barcamp Boston 2009 and it was pretty cool. Also tasty!
Having a scoop of liquid N was one of "Hundred Things to do before you die" items.

I think this is how they make those "dippin' dots" ice cream (which i love oh so much).
My guess would be that you would have to drizzle the (pretty watery) mixture into a pool of liquid N. I guess it would just burn off after a while and you'd have a nice treat.
Hmm... maybe I'll give it a try this weekend.

We did this at my elementary school when I was a kid!
(My teacher's husband was some kind of a scientist who had access to liquid N)
It turns out LN2 is cheap and easy to get, but a Dewar flask costs around $400. I haven't been able to find a place to rent one.
Ask for a thermos instead of a Dewar Flask. They're the exact same technology, but the term 'Dewar Flask' implies a much higher grade.
Remember not to seal the thing airtight unless you're trying to build a bomb.

Liquid N is a little difficult to come by. I need a dry ice recipe...
Also, it's really fun pouring liquid nitrogen into a bowl with a mixer and ice cream batter.
