10 Things to Do at a Birthday Party With Liquid Nitrogen!




Introduction: 10 Things to Do at a Birthday Party With Liquid Nitrogen!

About: Random Weekend Projects

10 tricks with liquid nitrogen that you could try at your next party, but probably shouldn't!

Step 1: Watch the Video!

WARNING:  These projects and results are depictions of my own personal experiences, which may vary depending on location, and modifications to project ideas.  There may be risks associated with some of these projects that I'm not aware of.  Liquid Nitrogen is -321F and can cause sever tissue damage and serious damage after prolonged exposure.  Use of this video content is at your own risk.

Step 2: Futuristic Ice Cream (Dippin Dots)

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 flavors in one, so go ahead and separate the colors into different containers, and give them a couple of minutes to melt. 

In the meantime, we'll need to fill a bowl, with liquid nitrogen.  This stuff is -321ºF (-196ºC), which means it well below the freezing point, of your party guests. 

Now if you try dripping your flavors in, one drop at a time, you'll notice they 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 ice cream, ready to serve, and enjoy.

Step 3: Chill Pills

Load up a bowl with mini marshmallows, and sprinkle liquid nitrogen over the top. 

The marshmallows should freeze instantly, but go 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 crunch into it. 

Now, if you flash-freeze a larger marshmallow, rather than eating it, try placing it on a plate and giving it a smack.  It'll shatter into a thousand pieces.

Step 4: Noise Makers

For this trick you'll need a glass bottle with 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 pour the liquid nitrogen, so the bottle is a quarter full, followed by a shot of hot water. 

You can see that when the horn is pressed into place, it becomes a crazy noisemaker, that blows all on it's own. 

If you get a few of these going, you can really make some noise.

Step 5: Balloon Blowers

When there isn't enough pressure to keep the horns 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 their own. 

It will save you the effort, and the gas inside is completely harmless.

Step 6: Chips That "Bite Back"

Find a bag of your favorite chips, and dump them all, into a bowl of liquid nitrogen, to sit for a couple of minutes. 

Now, it may look like they're boiling, but they're actually being cooled, to a ridiculously low temperature. 

When the boiling stops, feel free to scoop them out, and onto a plate for serving. 

If you try eating one of these right now, you might feel a sharp sting on your tongue, like the chip is trying to bite you back.  But if you give them just a minute, then try chewing with your mouth closed, it should take your chip eating experience, to a whole new level.

Step 7: Liquid Oxygen

Cut the top off an empty soda can, and fill it up with more liquid nitrogen. 

You can see that holding a flame into the can, will make it go out.  But if you let the can sit for a few minutes, the extreme cold, will pull oxygen out of the air, and trap it at the bottom. 

Now try dipping a super strong magnet into the liquid, and when you pull it out, you'll have liquid oxygen stuck to the bottom.  At least until it warms up, and boils off.

Step 8: Birthday Blowout

Save one of the candles from your birthday cake and hold it over the can. 

You'll notice that this time, the flame actually gets brighter.  This is because the nitrogen has evaporated, and left the oxygen behind. 

Pure oxygen is extremely reactive, and if we drop a candle down into the liquid, you can see it gets so hot, that the metal can actually melts in just a few seconds.  Then explodes, spewing molten metal all over the place. 

This is a trick that should be done outside, keeping the safety of you and your guests, as a top priority.

Step 9: Balloon Babies

Blow up a bunch of little party balloons, and soak them in a container of liquid nitrogen, so they shrink down to nothing. 

Then quickly scoop them all into a bowl, and stand back to watch the magic. 

Rising from a layer of mysterious 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?

Step 10: Fly Babies

Fill one of your small balloons with helium, and shrink it down in liquid nitrogen, like you did the others. 

Scoop it out and place it down on a table to see what happens. 

You'll notice that after a few seconds, it suddenly pops upright, then takes off like a little UFO. 

Your friends should be impressed, to see your little creation grow up, spread it's wings, and begin to fly.

Step 11: Kryptonian "Super Breath"

For this last trick, we'll need a shot glass, or a small condiment cup like this. 

Pour in a tiny bit of liquid nitrogen, and get ready to put it in your mouth. 

As long as you spit it back out immediately, you'll gain the Kryptonian power of super-breath. 

Just make sure not to swallow, or take too long getting it back out.  That probably wouldn't end well.

    Worth noting that swallowing liquid nitrogen can cause terrible stomach injuries:


    I've played with liquid nitrogen quite a bit and spent all day dipping an ungloved hand into the flask (isn't the Leidenfrost effect great) but I would hesitate to suggest anyone puts liquid nitrogen into their mouths.

    Aside from that, this is a great collection of fun liquid nitrogen demo's - thanks.

    An 18 year old girl in the UK called Gaby Scanlon had to have an urgent operation to remove her stomach after drinking a cocktail made with liquid nitrogen.

    As for putting it in your mouth, someone else had to have their stomach removed a few years earlier, so overall, it's just not a good idea folks :-}

    so, this is full of awful irresponsibility. I may as well add another, just in case anyone doesn't off themselves with the whole liquid nitrogen in the mouth bit. Fill a plastic bottle with the liquid nitrogen and screw the cap on tight. Really guys, LOX is used as the oxidizer in rockets. Please for the sake of your mothers, don't drop candles in it.

    I wouldn't want to show kids how to put liquid nitrogen in their mouths and molten metal is usually a bad idea at parties...
    These things seem like more of an outdoor weekend thing.
    Liquid nitrogen is not difficult to get but you should have a good container to store it or it won't be around very long.

    Cool.....but a little irresponsible.....liquid nitrogen is quite dangerous and if handle improperly, it can cause SEVERE burns and possible loss of body parts!
