Tomato power

This is what interrupted me from taking part early on in last night's chat & Gabbly chat.



This clock has been running for over 22 hours now. We bought "Lemon Clock" kit from Maplins.

Hi Multiveg! I've never seen anything like that before in my life!!! How does it work? It looks brilliant! Dexterdog

The things the wires are attached to are electrodes - the kit comes with a range of them, I was using magnesium, brass, copper and zinc (I think order matters, though I haven't stated them in circuit order). There are 20 experiments listed in the manual. Good value for £8 I think it was. The Science Museum do a Potato Clock - same sort of thing I think.
There's probably a chemical explanation - ah ha = wikipedia: http://en.wikipedia.org/wiki/Standar...rode_potential though this is still a little technical - it was GSCE/O level standard about 20 years ago.

Just works like a battery!

Anode and cathode emersed in electolyte equals power me thinks!

There you are, there's the portable heated propagator sorted! Tomato power!!

Update - although the clock was still "ticking" the tomatoes had acquired moulds of some sort or other, so they went into the bin. Have restarted clock now with potatoes - they'll probably "last" longer.

How interesting! I want one! DDL

When my husband was teaching physics we always had one - they are great fun and you can try all manners of fruit and veg. Bananas I seem to remember work very well. They are always a talking point!

Ahhh, runing on Micro Chips now eh? Shirley the tomatoes clock was doomed to failure
