The kids love it!
Works as advertized and is an exciting way to experience this type of engine. It got going so fast that it began to move across the table. Fun to work and watch and makes a great item to keep on my desk...along with the other Stirling gifts I have. Looking forward to putchasing my next item!
This device defines the word "power." I haven't finished my lesson plan for this, because I'm not a science teacher and I don't want to work that hard. I'm not sure if the magnets function solely as a levitating force, or if they also contribute to the spinning motion. Very cool unit. I would like to see what is behind the solar panels, but I don't want to ruin my spinner. Would have been interesting to watch its design develop (weight, length, size/shape of panels). Would be awesome to make one about 30 feet long. It might be quite unwieldy. Thanks. It's a great gift to myself.
Took it to work and was surprised by the people that would stop by just to watch it. My granddaughter loves to play with it using the flashlight.
My only complaint - it's not well balanced, so when it gets going, it has a tendency to bounce till it hits on the desk, or falls off. I've been trying to balance it myself, but it's slow going.
