I have a Thermos flask filled with liquid nitrogen.

Indeed, good suggestion.

I posted this thread at the wrong time really. Just home form the pub and all I want to do is sleep, but instead I asked for suggestions on activities to do involving liquid nitrogen :/
 
Some quick googling suggests:

Freeze a can of shaving cream and then peel the can away from the cream. Put the canless cream into someone's car. Let the oven-like heat from the car's sitting in the sun defrost the shaving cream. 2 cans will fill an entire car.

DO IT.
 
If you get one bucket to catch the stuff as you poor it....

Grab a can of lynx (or any spray deodorant), spray the can and pour some liquid nitrogen over the spray... Would be pretty cool to see that on film :)


Or you could even try setting fire to the spray and pouring it over the flames.
 
Dude the shaving foam one is so possible without the no-faceage scenario

Haha do it, and video it :D
 
Do the shaving foam thing, you know it makes sense!

The other option is to pour some into a 2l soft-drinks bottle which has been filled about a 1/3rd with water and very, very, VERY quickly put the cap on. You should have about 20s to get away from the bottle before it pops (if you get the cap on fast enough)
 
How did your Dad get hold of liquired nitrogen? lol :p

I want some to play with :(

He's a precision engineer. He uses it on the metals he works with to make them shrink by a couple of thousandths of a millimetre so ensure a tight fit between different sections of metal (or something), so he has to use it quite often.

Ahh cool :)

fill up a paddling pool of water and pour it in and see what happens!
 
Drink it

(Disclaimer: You will likely die if you do this)
I don't have Flash on this machine but a prof at Cleveland State Univ. named Jearl Walker used to drink liquid nitrogen (not actually drink it, but he put it in his mouth) as part of one of his lectures. He has a television show called the Flying Circus of Physics. I'm sure the clip is on YouTube somewhere.

you can pour it into your palm and rol it around without damaging your hand, but it does take a little practise!
 
Theres a video on youtube of a guy making a water melon explode with it, can't link due to swearies but it ain't hard to find.
 
You could do what I did the last time I got my hands on some. Pour a little into a plastic bottle, screw the lid on, and run like hell. It makes a loud satisfying boom. I started with small bottles and worked my way up to a 3L soda bottle. T'was quite impressive. :D

Putting it in your mouth = OK
Drinking it = Not OK
