we've discussed this before and I said I'd try...
talk to my buddy in the lab. he works with liq N2 alot (freezing cow embryos).
I also did some research and math. Practical problem is this:
a tiny amount of liq N2 becomes a huge amount of gas when vaporized. so it would be easy to overpresurize. a " shot" of liq N2 is more than enough to make an instantaneous glass granade.
I asked my friend how could I put a single drop of liqN2 in a bottle and there is no simpe answer.
a syringe: imposible.
a spoon? very hard, easy to overdose!
we have to do some experiments when he can get some n2 from the lab but I am not as exited as before.
I'd recomend very low co2 carbonation for the bottle and the syringe trick to get the creamy guinness head. I'm actively working on that now
... my friend is providing the syringes hahahaha!
