Grandfather/grandson project
It was a great science project for me & my grandson.We got into a lot of discussions about electric power for homes - what would be be like to power every light in the house with a bunch of potatoes in series, always changing the potatoes when they spoiled.

Works great, Daughter loved it.
Really nice set. Be careful with the zink items they bend a bit if you hold them from the top. It worked in 5-6 solutions. Tested them with a voltmeter for a science fair.

price is way too high
I am giving 4 stars because it works, but any potential buyer needs to know that this price is ridiculous. These can be bought in a toy store for around 15.00 to 20.00.
