Awesome and nostalgic

When I was younger, I had a toy that I particularly like playing with. It was great for teaching mechanical and electrical principles for kids not quite ready for erector sets and powertools.

All the electrical and mechanical parts are contained within sealed plastic cases, so it makes it very easy to snap things together and see how the parts inter-relate. I find it is very good for promoting free, creative play with all the different components.

The company has stopped making them, but they are available on ebay. Go search for 'Capsela toy' and you will find loads of options. I recommend the Capsella 1000 series.
