Diving Submarine

Back in the days when technology was a good guy, and cereal boxes  came with real toys, kids got diving submarines that they charged with baking powder and played with in the bath tub. Now kids can have the same fun again. We have found a (gray!) submarine, about 4-1/2" long, that can dive and surface up to a dozen times with a single charge of the baking powder that you get to supply. Comes with instructions and made in the USA.

Home-Grown Are Always Best

We’d start with triops, lovely little crustacean-ettes that have been around since Triassic days. You pick the Ghost Triops, see-through honeys, or the larger Gigantic Triops (gigantic among lesser beasts). In both cases you get eggs, baby and adult food, and a pipette. You add a bright light source, bottled natural spring water and a small tank. They hatch in a day or three, are full grown in a month or so, and have a life-cycle of up to 90 days.  Ages 8+.
