the demonstrations you are about to see arefor educational and entertainment purposes only, and are not intended to be duplicated. get out your container of liquid nitrogen,and grab a box of neapolitan ice cream. this is the type of ice cream that has 3 flavorsin one, so go ahead and separate the colors into different containers, and give them acouple of minutes to melt. in the meantime, we'll need to fill a bowl, with liquid nitrogen.this stuff is -321âºf (-196âºc), which means it well below the freezing point, of yourparty guests. now if you try dripping your flavors in, one drop at a time, you'll noticethey instantly bead up, and freeze solid. when you've got all the flavors you need,simply scoop the tasty pellets into a serving
bowl, and voila! you've got a futuristic icecream, ready to serve, and enjoy. load up a bowl with mini marshmallows, andsprinkle liquid nitrogen over the top. the marshmallows should freeze instantly, butgo ahead and let them soak for about 30 seconds just to be sure. the end result is a sub-zero"chill pill", that's perfectly fine to eat, and lets you see your breath when you crunchinto it. now, if you flash-freeze a larger marshmallow, rather than eating it, try placingit on a plate and giving it a smack. it'll shatter into a thousand pieces. for this trick you'll need a glass bottlewith a narrow neck, and a party horn with a little hot glue, added around the bottom.when it gets placed in the bottle, it should
make a nice, snug fit. now carefully pourthe liquid nitrogen, so the bottle is a quarter full, followed by a shot of hot water. youcan see that when the horn is pressed into place, it becomes a crazy noisemaker, thatblows all on it's own. if you get a few of these going, you can really make some noise. when there isn't enough pressure to keep thehorns going, try adding more hot water to the bottle, and place a balloon over the top.there will still be enough pressure shooting up, to inflate the balloons, all on theirown. it will save you the effort, and the gas inside is completely harmless. cut the top off an empty soda can, and fillit up with more liquid nitrogen. if you let
the can sit for a few minutes, the extremecold, will pull oxygen out of the air, and trap it at the bottom. now try dipping a superstrong magnet into the liquid, and when you pull it out, you'll have liquid oxygen stuckto the bottom. at least until it warms up, and boils off. blow up a bunch of little party balloons,and soak them in a container of liquid nitrogen, so they shrink down to nothing. then quicklyscoop them all into a bowl, and stand back to watch the magic. rising from a layer ofmysterious flowing fog, your little balloon babies, begin to grow right before your eyes,spilling over and covering the table. they grow up so fast, don't they?
fill one of your small balloons with helium,and shrink it down in liquid nitrogen, like you did the others. scoop it out and placeit down on a table to see what happens. you'll notice that after a few seconds, it suddenlypops upright, then takes off like a little ufo. your friends should be impressed, tosee your little creation grow up, and begin to fly. well now you know 7 different party tricks,with liquid nitrogen. if you liked this project, perhaps you'll like some of my others. checkthem out at www.thekingofrandom.com
