Dry Ice

I received my delivery from from Amazon Fresh this morning. My frozen items were packed in dry ice.  How cool is that?  I know people use dry ice to make fog around Halloween, so I thought it would be fun to show the boys.IMG_0727

We added some blue food color to some warm water…IMG_0729 

and dropped a small chunk inside.

It was fun to blow the “fog” all over.

If you blew all of the “fog” off the top, you could see the water bubbling.  The boys liked that, but jumped whenever the fog came toward them.

I looked online for some more experiments, and found quite a few.  So, we tried some…

We listened to the “screaming” of a spoon (heated by the fire from our gas stove for a few seconds) that was pressed against the ice.

(I know,  a photo doesn’t really help here…)

Later, we smashed up small chunks of the ice so that they fit into a water-bottle, and put a balloon on top. (then we let it expand while we did some other experiments.)

Owen added dry ice to soapy water…IMG_0753IMG_0756     

Jack added it to milk.

(He wanted to drink the milk, but Mama nixed that idea.)IMG_0759

I added some red food color to the milk so you could see what was happening.

This is how big Owen’s balloon expanded from his dry ice.

We also made a balloon for Jack.IMG_0767

Owen suggested we dump the dry ice into Jack’s balloon and then tie it, so we did.

Here is Owen’s balloon (with no dry ice) and Jack’s balloon (with dry ice.)

Jack liked that you could see the “fog” come through the balloon. (If you click on the photo, you can see see it in front of his face.)IMG_0781

Here are the same two balloons a little while later.  Owen is not too pleased with how the experiment was turning out…He wanted to trade his balloon for Jack’s balloon.IMG_0782

Until Jack’s balloon exploded!

(which Jack thought was VERY funny despite the fact that he was holding it.)

I had a few more ideas, but that will have to wait for another day… when we can go outside…
