what you have to do it get a coke or sprite or any bottle chop the bottem off and turn it upside down sitting in a cup or something but the brine shrimp in salt water (i pefur to use water staraight from the sea) and have it bubble non-stop place it next to or near a light as it has to keep a bit warm when they hatch you will be able to see them
if that heaps you some body might be able to help you a bit better
