Nah, thats not what I mean.
A little history first:
I have for years been working in the same department, where I had to share a woodshop with several other passingby employees, where noone felt any responsibility for it but me, and as a result it totally exploded in clutter, mess and left stuff that most possibly got wrecked by the kids, leaving the impression that te woodshop was a place you went when you wanted to destroy stuff... That left me with years of not having any desire to go in there anymore. Lots of my coworkers decided that as it was already messy it might as well be used as a storage for everything else they just used and might (or most possibly might NOT) ever use again.
This year (after the summerbreak) I got transfered to another department that hadn't had a man work there for close to 5 years which my boss wanted to do something about, and I got moved there as I wanted a new challenge as well. Their woodshop has been run (5 years ago) by a guy who was so perfectionist and hotheaded that the kids didn't feel like going in there. That how ever means that he had the tidyest most uncluttered woodshop of everyone as he left/got sacked the workplace.
Now it is ALL MINE (MUHAHAHA

Now I made a workspace where I want something interesting to happen at least once a month. Sort of a miniature lab or exhibition. That means that I am going to be making soda-fountains etc. I am also going to build a very small railroad there for the kids to help with. W had a Märklin trainset with rails that I bought with a coworker back in '98, but it never got used after our initial succes. Weirdly the locomotive disappeared, and as such I need to go buy another one for a fortune (unless Raillo can tell me that I can use any kind of locomotive and I dont need to go spend 55€ on a standard Märklin locomotive. Oh and it would be cool to have a picture of your setup Raillo to show them!)
My real question is: Do you know any cool experiments that I can do (household stuff).
So far I got:
The soda-fountain - The Mentos One.
The baking soda and vinegar vulcano
Floating experiments - what floats, what wont.
If I can make it work - Quickfreeze beer
Anyone have any other cool kids experiments? Can actually be anything that would be fun for kids to watch. I am trying to create a buzz in my shop. (Last I had something create a buzz it was something as simple as an austrich egg with the story of Columbus smashing the top of an egg on it. Kids was all ears of how the story went.) So anything goes.
