Poor man's "Liquid Nitrogen"

reloadedditto Says:

Nov 17, 2009 - High school budgets are state and national mandates on what must be purchased. We have to do dissections in Biology and Anatomy. Frogs, crayfish, worms, starfish, grasshoppers, pigeons, sheep eyes, cow hearts, minks and cats are expensive and are required to be dissected by my particular state. The National government requires that 20% of a high school science class must be in the lab or hands-on learning.Because of this, novelties like liquid nitrogen get passed and cheap alternatives are used

Nov 17, 2009 - thats amazing! but how did the center container become filled? was from the gasses escaping and pouring in? why did you wait until it stopped "boiling" ? what would have happened if you didnt? what are the dangers here? can it explode and burn youand your audience?

Nov 18, 2009 - Remember he put all those holes in the small bottle? That's how it got filled. The dangers? Like he said the liquid sticks to your skin.

Nov 18, 2009 - cool i never knew that...but doesnt it ussually smoke like alot?

Nov 19, 2009 - would you be able to use this application for molecular gastronomy cooking techniques as substitute for Liquid Nitrogen?

Nov 20, 2009 - "Freeze the daisy." Love the way you say that.

Nov 20, 2009 - A hammer is easier to break dry ice blocks.

Nov 20, 2009 - Cool if i can get some dry ice im gunna try this... and love how you said the freeze the daisy part.

rousod Says:

Nov 21, 2009 - you should put a plastic bag and then brake it with your finger. This would be cool!

gevelegian Says:

Nov 21, 2009 - Can you keep the dry ice in a freezer? For preservation?

responsedude1 Says:

Nov 21, 2009 - freeze ur nose please

spotlightman1234 Says:

Nov 21, 2009 - no you cant it will make the freezer or fridge too cold and break it or fling the door open plus the temperature difference is too great to make much diffrence rember the risk 0f suffication

Nov 22, 2009 - Can you make yellow cake ?

gevelegian Says:

Nov 22, 2009 - Why thank you for the info... you see? If someone like mine wouldn't have known that... it could have caused a catastrophe! :) Luckily dried ice isn't available everywhere here.

Nov 22, 2009 - you make no sense.

Nov 22, 2009 - keep dry ice in a freezer? Dry ice thinks a freezer is hot. Dry ice lasts one or two days in a thick styrofoam box with a thick lid. To preserve dry ice, put it in many layers of styrofoam with aluminum mylar reflector foil beween each layer. Also, small amounts of dry ice have a large surface area, so they won't last long. To make it last, buy a large amount, because then the large volume cannot heat up, while the relatively small surface keeps the interior cold.

Nov 22, 2009 - oh mah gowd thats so freakin awesome :O

puerkola Says:

Nov 22, 2009 - u should use gloves you idiot

wbeaty Says:

Nov 22, 2009 - use gloves Dry ice isn't for kids. And kids should always use gloves when handling hot or cold objects (such as hot bread or potatoes from the oven.) Otherwise they'll get hurt, because they don't know the tricks that allow barehanded work.
