"Home Made" Liquid Nitrogen, for next to nothing!

Or, poor man's liquid nitrogen. I'm in college, but unfortunately no chem classes, nor do I have the money for a Dewar's of my own to have filled. I heard of this technique from a friend of a teacher's son's maid..or something, it was a while ago.

Full credit for this idea belongs to wbeaty over ar Youtube,

I'm just the instrustables messenger;)

Step 1 Supplies

- Two pop bottles or equivalent. (1 2L, one 354ml or whatever the personal size ones are)
- Dry ice(Pellets probably are the best option)
-99% isopropyl alcohol( Can be found at most grocery/drug stores.)
-Something sharp to cut the bottles apart with.

how long does the alcohol stay at freezing temperatures?

[junits15]

not liquid nitrogen, just cold alcohol

Are the two pictures of frozen weed?

Haha, it's a maple leaf little buddy.

[bowmaster]

Oh!!! Now I see it!!

[walfers1]

how do i make a holding tank fo liquid nitrogen

[Fridge Gnome]

would this shatter a rubber ball?

[rerat]

I would assume so, if you let it freeze long enough!

[lasr1]

Well, only one way to find out!

This is a lot like wbeaty's demo on "Poor man's "Liquid Nitrogen" Youtube http://www.youtube.com/watch?v=d11TFkeqbwY. He even describes that it will stick to you like napalm in his description. If you were inspired to make an Instructable because you saw hid demo, you really should give some credit to where you got the idea from.

The napalm comment however I derived myself after having stuck my finger in the mix. Haha.

[bigmike233]

did it burn ur finger???

[66411]

I also put a bit on my fingertip when I made napalm, this was to feel the viscosity of it I presume that the author as I, did this before testing the burn characteristics of napalm.

[rerat]

Holy..you're right, I was absolutely no recollection of where I knew about this from! Adding credit now, sorry wbeaty!

[rimar2000]

Awesome! Thanks.

No problem! make sure you check out wbeaty's video! It is such a fun thing to see something like a flower, shatter like glass.
