4M Diving Submarine - Science Toy

works so great in pool

just thought about this out of nowhere, when i was real young got this as a prize in a box of [serial< [sorry i can't spell] thank you, glad to have this again ✌😉

When I was a kid, Kellogg's Sugar Pops offered a diving sub (reminiscent of the first Atomic Submarine, the Nautilus) as a toy for just $0.25 and one box top. That original design has been re-issued by many different companies over the years and is still available to this day. I have one of those original subs as well as several later issue versions. Therefore you might imagine my surprise (and delight) to discover this NEW design (that of a modern Attack Submarine), which still retains all the fun of that original cereal premium. Basically, the operational mechanism is the same for all diving sub toys; i.e. You remove the friction-fitted periscope assembly and fill the revealed chamber with some baking powder. Pop the periscope assembly back in place; swish it around in the bathtub (unused aquarium, large jar or large glass) briefly and let it go. The sub then dives and resurfaces until the baking powder is depleted. NOTE: do NOT use this in an aquarium that contains live fish as the baking powder/water reaction could be toxic to fish, snails etc.) TIP : As long as there is NO baking powder in the toy, it could be used as a novel "ornament" that would add a nice touch to the bottom of any aquarium that did contain live fish.

Haven't tried it with the baking powder so I can't say if it works as advertised. Who wants to fool with filling this with baking powder all the time anyway? We got it as a general bath toy. My son likes playing with it but it is t-i-n-y. It looks and feels much smaller than it's actual dimensions suggest. In hindsight, I wouldn't pay more than a dollar for this toy. It certainly isn't worth nearly $6.

This toy does exactly what it says. It does dive and come back up. However, my five y/o got pretty bored with it after a few minutes. But he does ply with it every few days so it's not a total waste and for the money, pretty good, I'd say.

Not very much fun. Its basically a plastic submarine, forget about baking powder thing, it works but barely, the water needs to be really still and its not fizzy or anything, just a few bubbles.

I actually bought this as a surprise for my little grandson. He saw one in the gift shop at Georgia Aquarium. He didn't buy it and really wanted one. I phoned the aquarium but they were sold completely out. I was lucky to find it on Amazon. We've had sooo much fun. Goes forever with a little bit of powder. Nice to have simple toys. Sandie

This is a toy that keeps them coming back. I then purchased the frogmen that also dive and resurface.

Its too small and some times it goes down and donot come back - done with cheap plastic

The old Kellogg's subs worked much better. It was unstable and the action didn't last long. The seller is not responsible.

Bad quality
