A multistage NTR to LEO might not be that farfetched. Well, I suppose, if you use a cryogenic fluid and a sealed source (Co-60?), it would be a NTR.

This is marketing. Water rockets are all good fun, but lets not kid ourselves it is not a saturn-5 Yes. This is marketing.

As Deviate-to-excel says, "space" might be "that empty parking lot" or "the lake". The alternative to space would be to launch the bottle into a crowded subway train, known as "no-space". This is not recommended. “Space” as in “somewhere with plenty of nothing”, for example “that space over there”. As Deviate-to-excel says, “space” might be “that empty parking lot” or “the lake”.

It was rather spectacular (to me) and had the added bonus of getting one soaking wet when it launched. Assembled it stood about a meter high, and was made of hard plastic, thus it eventually failed re-entry and touch-down on the concrete parking lot I foolishly used as a range on afternoon (previous missions had been flown at the Lake.) I had forgotten about it until I saw this item. As for saying you're going to put one of these things into space, well how do you spell m_a_r_k_e_t_i_n_g Had a three-stage water rocket back in the ’50’s when I was a kid, it was a store-bought toy that worked from a launch pad, and a bicycle pump to charge it (not included.)

On the other hand I doubt kevlar will provide adequate containment.
