### ⭐⭐⭐⭐ 20,000 Micrometers Under The Sea
*by S***N on March 5, 2012*

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.
