Yeah, the ads were always tempting in the back of those kid’s magazines in the 70s. Along with the offer of X-ray glasses that allegedly let you see through girl’s clothes.
Sea Monkey Kits
I used to grow them to feed my fish. We called them brine shrimp though.
@TheOther1 I did as well (when breeding Betas, a.k.a. Siamese Fighting Fish). I think the “Sea Monkeys” might be a slightly more exotic strain of shrimp.
