Dry Ice Moves on Mars
Heard about the rocks that move strangely in the desert? Could that be the same type of thing as the dry ice?

The Joys Of Dry Ice (The Adult Toy)
Hint: Large Gatorade bottle works loudest and best for dry ice bombs, plus they expand to the size of a frikkin' basketball sometimes-
oh, chlorine and ammonia works, too if you want a poisonous gas bomb-

Giant Dry Ice Bubble Experiment!
I like the little crashing sound effect they put in when the bubble burst.
Dry ice is fun stuff.
Fish Boiling In Aquarium PRANK
>> ^Auger8:
Wouldn't the dry ice they're using bring the water temp. down so fast it would throw the fish into hypothermia or shock?
may have just been Seltzer tablets

Not to mention raise the CO2 level to suffocate the fish.

Popping a Mercury Filled Balloon in Slow Motion
@MilkmanDan When it comes to mercury I'm of the opinion that the educational benefit of playing with it is fairly slim compared to the danger, so why risk it.
On the other hand, my kids are doing awesome things in science now that I never did at their age in school (grade 2/3/prep). They've had dry ice to see what it does (of course, I've done that with my kids a number of times too, too much fun), they've had balloons filled with hydrogen exploded in class, and a few other things I've forgotten. The main thing is that I thought that they may well be limited in what cool science they get to do at school, but at least at our kid's one they seem to be doing plenty of awesome stuff.
Starter Fluid Tire Inflation [MythBusters]
>> ^rottenseed:
So the limiting reactant would be the starter fluid and the air in the tire. Oxygen to be more exact. Because you want enough forces to seat the tire, but not so much it removes all of the gases from the tire, maybe they should have tried less starter fluid. If that's depleted in the reaction quickly leaving enough energy to seat the tire, but also enough oxygen left over from the reaction, you might end up with a working tire.
Somebody please double check my thought process, but I think it's definitely worth more experimentation.
Would be one to test, but I think you'd end up with the same problem. End of the day to jump the tyre back on the rim you are going to be filling quite a lot of the inside of that tyre with the hot gases from the combustion. You might get less deflation with less accelarant, but I'd think you'd start with a lower pressure within the tyre even before the gases cool, so you wouldn't gain much. Thats my guess anyway.
Now maybe if you did this, and at the same time dropped just the right amount of dry ice in with it you could get the tyre back on the rim AND get it pressurised without the need for some sort of pump. Ofc, dry ice is not exactly something you tend to have stored in the glove compartment...

I didn't so much as watch a video about Dry Ice as I did a Gorilla Glue commercial with some dry ice fun thrown in.
