Author: LianeRating: 4 out of 5 starsIt was easy for my eight-year-old to assemble. We used half liter bottles, which might have been too small because the vessel tipped a bit when we turned it on. We took it to an open patch of water, and it tended to turn into the wind rather than go straight with the wind behind it. It might have been because our water bottles were too small. My son had fun, though, and understood the science concepts behind it.
