Ok, back to business. I bought this book a while back, but haven't really used it.
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.
For this, I only needed a bottle, a balloon and an old banana. check, check and double check.
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.
Aren't you proud of me?
The kids still wouldn't help me.
Trust me, I kept asking.
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.
and waited a day.
Sure enough, bacteria flocked,
as the banana decomposed,
and released a gas
that started to inflate the balloon!
And then I threw it all away because I'd had enough.
But, I like this whole science thing.
I may have to try another experiment soon.
