I had one of those submarines.
We used to get them in boxes of breakfast cereal.
Yeah. I don't recall whether it came in the cereal box or if I sent a
quarter offf somewhere with a boxtop.
I sent off a quarter. And it was a "frogman.' Never saw a sub.
It was good for a month waiting for the mail, and then 5 minutes of
watching it go up and down.
Money would have been better spent on a squirt gun.

There was one box top toy that was actually quite cool. It was a
plastic rocket that you filled half way with water and then mounted on
a small air pump device with a trigger assembly. The idea was to pump
up the remaining space in the rocket with compressed air and then pull
the trigger to launch. It worked pretty well as I recall.
Yup I had one. The trick was to get the optimum amount of water. It
wasn't exactly half.
... Then we discovered dry ice. Screw that wimpy pump.
The ice cream man started making as much selling dry ice as he did ice
cream. I suppose the safety nazis would lose their minds about
something like that these days.
I can remember making rockets out of aluminum tubing. Crimp the nose and
neck down the exhaust and fill with aluminum and sulphur powder.
