Yellow,with wire

We used this tool to teach a child how turbines work in both wind and water. The child struggled with books and this demonstrated exactly how turbines work.

Good for demo. Fairly delicate so don’t survive that long when kids are using them but cheap enough to replace. Usually last around 10 workshops with 30 kids each having a go.

This simple device can teach anybody how a wind turbine can produce electricity. Works immediately after a few minutes of assembly.

If little use !!

Functions well once built. Requires soldering together so not really suitable for younger children as adult intervention is required. Wires are very short (approx 8cms) so if you’re looking to conduct a worthwhile science experiment you’ll need extra wire to extend it. Also worth noting the LEDs included are RED not clear, my son used it for a school project to show how we use wind for home energy but all lights inside his model house glow red 😬.

It does work if you have a good source of air I.e. a hairdryer. Blades are a little flimsy and would easily snap if knocked but they work.

Well made mini generator. Great fun to see it light up when the wind blows. Worth the money. I mounted it outside on an arch in the garden in an upturned plastic jar. My grandchildren love to watch for the led coming on.

It was so good 😊

muß noch testen

Como en la imagen funciona perfectamente

Ich habe alle zusammengebaut bekommen und in einem Würfel als Modell eingebaut. Die Begeisterung bei den Kunden war groß.

Come da descrizione.....funziona bene ed è stato utile per quello che mi serviva

Excellent
