Ok, back to business. I bought this book a while back, but haven't really used it.
So, to
The only problem was, my boys were totally not interested in doing anything.
They were deep in Lego land, building a dwarf castle and a Star Wars ship.
I chose an experiment that I actually had the stuff to complete it. Stuff on hand, you know.
For this, I only needed a bottle, a balloon and an old banana. check, check and double check.
First you much the old banana until all the lumps are gone.
It's kind of gross...but also kind of satisfying.
you have to slide the banana mush
into the tiny opening of the bottle.
I used a plastic knife to do this.
It was messy.
Ta da! Banana mush IN the bottle!
Aren't you proud of me?
The kids still wouldn't help me.
Trust me, I kept asking.
The only balloon I could find was a water balloon,
which is thicker than a regular one,
so maybe not the best one to use,
but oh, well.
I put it on top,
and it just laid there all limp like.
Sad.
Then I set the bottle in a warm, sunny place,
and waited a day.
Sure enough, bacteria flocked,
as the banana decomposed,
and released a gas
that started to inflate the balloon!
Woohoo!!
But, I like this whole science thing.
I may have to try another experiment soon.
