Looking for some fun things to do with Dry Ice?

post #1 of 7

A package I am going to be getting in the mail will have some dry ice in it. I was thinking about some fun experiments we could do. Anyone have any good ones??

I've not done anything with dry ice but I've used his site before successfully--the ideas look good here. He has the safety information you may want/need too.
I hope you have fun!

We went to a science fair, and their was a demo where they had mixed dry ice, colored water and a little dish soap. They had it bubbling away in a beaker like some kind of mad scientist's concoction. I don't know that it's especially educational, but it was really cool!

We own a children's science education company, and we do TONS of stuff with dry ice. The kids just LOVE IT!

Take a quarter and hold the block of dry ice in your hand (with gloves obviously) push the quarter into the ice, so it "cuts" a line in it... then place the quarter in that slot that the quarter carved. The quarter will begin to "shiver" you can explain the science behind it... that the quarter is on average 180 degrees warmer than the ice, so it's heat is forcing sublimation (the release of the gas) so that gas release is what is moving the quarter.

You can also make a spoon scream, when pressed against it.

You can take a bowl of water and add some dish soap then drop the dry ice in (if you break it up, it will sublimate faster and will give a bigger "wow") and it will make HUGE bubbles over the bowl.

We have a "shower" we constructed that we have a long tube, and a curved top that we dip in bubble solution... so we make gas filled bubbles that are awesome, but that one can't really be duplicated at home without the contraption.

I love dry ice

Peacemamalove,

There are tons great dry ice experiments all over the internet. Youtube has a lot of them. Another great resource is this dry ice website. They have lots of experiments. One of my favorite things to do with dry ice is just add it to water. Kids love the fog!!

Saw some nice geeks at Georgia Tech blow up a 2 liter bottle with it in an empty parking lot one night. Best to leave that for college.

Just be careful with that stuff.
