Um well I think the packet is actually referring to the fact that any remaining eggs will come to life if you add water after drying out the tank.
However in the wild (of course this is brine shrimp not Sea-monkeys) they have adapted to their environment and that environment periodically dries up. I'm not sure the adults come back to life but certainly their eggs do even after long periods of dryness.
But just out of curiousity (because if what you're suggesting REALLY does work actually, I will be so excited) I'm putting a single sea-monkey (a dead one) in a little bottle cap and I'm going to dry him up and put him into the water later. I'll let you guys know if he's the one to come back to life.
Don't worry I'm just testing... not challenging you or anything. Sorry, this would be awesome if possible though.
Hi you guys... um I'm afraid you must be misinformed... the Sea-Monkey revival thing was a total failure. The sea-monkey dried out and I put in some bottled water... when he 'resoaked' his tail came off and his limbs drastically swelled up. There was no sign of life and if anything it just made him look mutilated.
While it's a very cool idea I'm afraid that the way the Sea-Monkey corpse reacted to the re-introduction of water really only supports the opposite.
