Ok... first let me say, anyone that tries this is on their own.

I did some shows awhile back and decided to try this out as a performance.
My joke was,
"what is the opposite of fire eating?
well, fire **iting, but I really don't want to do that!
So I thought the closest thing to the opposite of fire, would be ice.
But ice eating isn't all that amazing.
But then I thought, it depends on what kind of ice.
What about dry ice! Frozen carbon dioxide!
-100 degrees! Now that is amazing."

So I took some dry ice, threw it on the ground and busted it into chunks.
Dropped one chunk into some water for the mystical effect.
Then with a pair of tongs, I picked it up and put it in and out of my mouth.
Eventually dropping the piece into my mouth and blowing out smoke.

How do you do this?
Well, just keep the ice moving around in your mouth.
If you do, the saliva in your mouth will easliy protect you from burning(frost bite).
Just blow out, and there will be smoke coming out of your mouth.

It actually worked pretty good as a performance.

It's just a little known fact that I learned from Mr. Wizard. The first science guy.

Have fun... but be careful. It can hurt you. Keep it moving!!

Nice thanks...

The other advise..
A lot of people don't know what dry ice is.
Teach them in your performance.

Randi

Sounds interesting thanks for the share.How do you keep dry ice dry when going to a show.How long until it melts?

I buy it on the way to the show and wrap it in a towel.
Don't plan on keeping any after the show.
Even if you put it in your freezer, it would be melted by the next day.
But will easily last for the night.

What size did you put in your mouth (a small sugar lump?)
What (smoke producing time)/size ratio would you indicate
Even if you move it constantly in your mouth, your mouth should somehow get colder and if the risk of forst bite is minimal at the start, does it increase with the time or the size of the dry ice you put in there.

I'm very interested but very scared: can you put a short video on Youtube (even bad quality filmed from your computer)?

Congratulation for your initial courage anyway. It brought me back 50 years back when I attempted my first fakir feats piercing cheeks and other body parts: it didn't hurt but was so impressive that I nearly feinted

:thumbsup:

I put about a ping-pong ball size in my mouth.
It will put out a pretty big flume of smoke.
Which is just the dry ice melting. So it's carbon dioxide.
I have never even came close to hurting myself with this.
It's much safer than fire eating.
You don't have to keep it moving a whole lot.
Just jostle it around a little, it doesn't take much.
The heat of your mouth starts making it evaporate.

Don't be scared, it's not hard at all.
I may have some footage of me doing it.

Ice regurgitation

Thinking along cooler lines, I remember seeing a chemistry teacher actually drink, yes drink, Liquid nitrogen (if you can get some!). It was the most exciting thing I have ever seen.

The "trick" is that it is actually impossible to swallow a smaller amount it. If you pour a bunch in your mouth (dont aim down your throat, but more like in your mouth, be careful not to get your tongue or lip stuck on the container) It instantly evaporates with no harm to yourself. It is actually not very hard to get Liquid nitrogen, especially if you were to just walk up to a hospital, or look up a local place. It can be stored in just a regular thermos as well.

Yes... I have seen Mr. Wizard do that too.

I would love to try it, but that's even more scary.

Randi

I've done this many, many, many times.

I start by bare handed juggling three pieces of dry ice, then catch each piece in my mouth. They are pretty small no where near ping pong ball size, but large enough to be seen from the stage. Once I produce a large plume of smoke I start to chew the dry ice up (I don't swallow it, instead just let it all fall out of my mouth) it looks like I eat it.

But that's mine... If I find out someone started doing this, I'll kill you. Seriously though.

This sounds like a winner.

Wow. How long can you touch the dry ice with your bare hands before it burns?

Very nice - although I wouldn't be too keen to do it.

Just clearing this small fact up for anyone that has not worked with dry ice before, Dry ice does not "melt" like normal ice at room temperature. It sublimates, in otherwords it goes directly from its solid phase(ice) to its gas state without a liquid phase.

Also, the potential for fatal accidents with both dry ice and liquid nitrogen definitely exists, especially with the liquid nitrogen.

If you don't remember to breathe through your nose while you are eating dry ice, you can pass out, and possibly die. The normal CO2 reflex should keep this from happening, though.

The bit with the liquid nitrogen is another situation. Nitrogen does not trigger the breathing reflex.
