For a kids project this gives you everything - 4 copper/zinc elements + watch that works at low voltage.

You can of course do it much cheaper: pennies (copper) and screws/nails (zinc plated) but then you need to solder/drill wires to them and unless you have a digital cheap wrist-watch to mod (solder wires to battery contacts) thus this saves hassle. A LED - even blue with low voltage - won't work with just 2 fruits (lemons, limes, etc.) you need at least 3 and generally 4 thus make the project a lot bigger.

Thus while expensive it does work well thus recommended.

Cheap but great fun to do with kids mine are 8 & 6
it only took a few minutes to make but they really enjoyed doing it simple enough to not cause arguments and easy enough they can do it alone with very little help,
They were very excited about what they created and both took it to school and there class were amazed and teachers also

Can't imagine it will last very long but for a cheap bit of fun its worth doing

this is really simple but really impressive way to introduce children to some scientific ideas - lots of fun and easy to put together.

Bought for my 6 year old nephew at Christmas - he was curious and amazed that he could power a clock from a lemon! Simple instructions and a nice explanation on the back to tell him how it worked. Quick service.

Kept my 5yo busy for well over an hour. After a lemon, he tried other fruits & veg, and some liquids.

My son loved it, he is at that age of experimenting and was fascinated so much so we have purchased a few others. Fast delivery, good price
