Dry Ice!

And as for my science club, I did my most epic class of the year, if not of all time: DRY ICE!

Not only a dry ice party, I Halloween Dress up dry ice party!

I spent all morning running to Lethbridge to get it (the man was super kind. I told him I wanted 20 lbs and he said that would be $70 and I was crest fallen, so he asked what it was for and I said it was for classes to to science experiments with kids, and he gave it to me for $20.) You have to go to a welding supply store in Canada to get dry ice. In the US you can get it everywhere.

I had tons of moms and Dustin helping me, and we did it all: we did huge bubbles and small bubbles and even "boo" bubbles, we did fake liquid nitrogen to freeze gummy worms in 30 seconds, we made a carbonated drink and ice cream, we put out fire, we wiggled coins, we had floating bubbles, we "carved" a pumpkin in an instant, and we blew up balloons (I'm sure I'm forgetting some of the stuff we did.)

But not only did we do all that, we did it TWICE! There were almost 40 kids in total. Crazy

The only thing we didn't do twice was....ummm...a dry ice bomb.

Not sure the neighbours appreciated that.

Don't you love the endermen? Maxwell made that hat, and its eyes glow and can hold speakers for the endermen song to play.

States of Matter and Polymers

And as far as extracurricular that I'm in charge of, science is going great. THERE ARE SO MANY KIDS! There were 20 (TWENTY) kids in my older class one week. That's as big as a "real" school!

One day we did a club about the three states of matter. They were pretty cute when they tried to blow up a balloon that was in a glass beaker. They turned very red in the face:

 The kids' favourite day is, of course, polymer day where we play with oobleck (cornstarch and water) and make our own slime. We also put pencils through plastic water bags and skewers through balloons among other experiments.

And this week we did the changing states of matter which had exploding film canisters, lots of ice-water-steam demonstrations, and the BLOWING UP OF A MICROWAVE. yep.

Well, my microwave is actually still intact. But the plate I put in it is shattered. I was trying this experiment:

But I didn't watch the video in preparation, and I thought I would just put this entire bar of soap that's at least 4 years old in my microwave and that it would work. Yeah, it didn't, so I thought it needed more time....then more time...that bar of soap is all dried out and just shattered my plate which sounded like the microwave exploded.

But at least blowing up balloons with baking soda and vinegar worked (Just look at the delight on William and Abraham's faces!)
