It's just carbon dioxide, isn't it?
It can't have done much, if anything.

It freeze-burns your skin if you touch it.
So on the inside, it must be a bit ouchy.

Once it's in a drink it can't stay solid for very long at all, surely?
I don't know, it's almost a decade since I did any chemistry related stuff.

Not very long at all, no, but it depends on the size of the piece.
If you managed to get one into your throat, or further, you would be looking at some serious convalescing.

I have learned something today.

It's suprisingly resilient.
it has a high latent heat of sublimation, so it needs a cockload of energy to turn it to gas.

It's really efficient at chilling drinks becauase of this though. I shared a big house in North London during my PhD and we pretty much perfected the bath of salt, dry ice and water for chilling beer. about 30 seconds for a can.

i was thinking asphyxiation
Would it not give off loads of co2, starving the body of oxygen?

Not unless you inhaled it.
you don't breathe through your stomach.

I was thinking there would be a constant stream of co2 coming up your esophagus, which would in turn be inhaled whenever you breathe.

nah, your oesophagal sphincter closes when you breathe.
Or at least it should.

It'll burn all the way down causing damage.
And will then turn into gas in the stomach. If it touches the stomach wall it could freeze that causing much pain and damage.

So yeah, it would suck.

nah, it doesn't burn on contact. See below.
