I always wanted to buy it, but by the time I saw the first ad, it was a lot more than $7. As the years went on, the price kept going up on a regular basis; it felt like the price increases far outpaced inflation. Here’s one article, there are a number of other articles you can find – http://secretfunspot.blogspot.com/2007/12/polaris-nuclear-sub-photo.html. Glad I didn’t buy it. Some of the articles are a lot more vocal on the subject.

YouTube video – Unboxing Polaris Nuclear Submarine | Houseoftheunusual – YouTube Video: https://www.youtube.com/watch?v=hR2M9cUEQEc (around 30:07 minutes long). Doesn’t show it being put together.
I don’t know if any child drowned using this toy, but cardboard plus water is a bad combination.
