Don't normally plug stuff, but if you haven't tried this magazine, its worth a look if you are interested in electronics.

One of my favourite projects from last year, must get my soldering-iron out:-http://www.elektor.com/magazines/20...m-for-elektor-usb-daq-card.639080.lynkx?tab=2

Cool project! Its been too long since I've etched myself a PCB and built something cool - chemicals and hot objects are just not kid-friendly enough . That's OK, here is my next project:

A baking soda volcano? I hope you're not serious, tblaxland.
Why I remember a school science fair where baking soda volcanos were banned.

Nice, suppose a scale model of Krakatoa isn't imposible?

I do like those mechanical/software projects, lots of fun there. Sure I've got a few model servo's around somewhere...

I'm serious - well I was, now I'm having doubts. Are these too dangerous? It seems a common enough kids experiment around here and I figured it would be safer than the the hydrogen peroxide version:

I could see that it could become dangerous if you tried to trap the reaction by putting the lid on the bottle and building up pressure, but I wasn't planning anything like that. I've never heard of these being banned before...

Not impossible, but I was not planning on something so explosive

No, they definatley were not banned due to unsafeness, they were banned because every kid did one and there was no variety.
I doubt it would become very dangerous if you capped it, unless you did something really stupid like put you head right over it.

I suggest you do something original. Maybe use real lava .

Ah well, no concern there. My kids have definitely not seen one before (they're only 3 & 4) so they'll still get a kick out of it :speakcool:
