4M 403378 Build Your Own Wind Turbine Science Kit Boys & Girls Age 5 Years+ Watch this working wind turbine capture the winds energy and turn it into light. This kit will teach you how this vital renewable-energy technology works. BRAND NEW & SEALED
Bought this as my 2 yr old grandson is fascinated by windmills and wind turbines. I built it easily as per instructions. Used a plastic 2l soda/lemonade bottle as per instructions. I actually used sand grit to fill bottle rather than filling it with water (gives it a much heavier weight) In addition put bottle into a cheap garden bucket, placed bottle in middle and filled remaining sand grit around it. This made it a sturdy foundation (and very cheap to do). I would suggest doing similar, if you are prone to strong weather winds, otherwise bottle would easily fall over unless supported (albeit weighted)
Turbine works well - had gale force winds and it stood the test. Light works well as turbine sails spin in the wind. Instructions stated to put lotion oil on swivel fixture, I used 3;in1 oil, works a treat.
Can now place turbine anywhere in garden - children love it. The beauty of it being what I have done, younger grandchildren/toddlers can see it and touch it with out fear of knocking it over. They can also see much to their eye level when light comes on when sails spin.
Would be useful if maker could make and addition base clip to secure Wind Turbine to a long broom handle or similar, this would add another versatility rather depending the need for a soda bottle top - only a suggestion.
Would highly recommend - for all ages
