Lobster eggs work for me. Wanted to try Pauls technique but was never able to get things dialed in and working. He really should sell them premade *hint*

i found it a little confusing at first too, but mostly because i was overthinking it.
i got a length of 3/8" rigid airline tubing tall enough to reach from the sand bed to about 2 - 3" above the rim of the tank.
then i got a small plastic funnel and fitted it to one end of the tube.
next i used a lighter to warm up the other end of the airline tubing, about 1.5" from the end. don't get it too hot, it doesn't take much to make it pliable.
then i very carefully bent at the spot where i heated till i had a 90 degree angle. using a pen to make sure the inside of the tube stayed wide open.
next i got an old NLS food container, and drilled a hole in the side just big enough to allow me to slide my newly bent airline tube in to. you want it small enough that you get some resistance, so that it can hold the tube without glue. (i prefer not to glue this together since it makes it a little easier when you need to clean it later)
then i took the lid off, and using a dremel tool cut out the center of the lid, leaving just the outside ring (kind of like the ring on a mason jar). then i took some pantyhose and stretched them over the container, and used the newly made ring lid to hold it in place. then carefully trimmed the excess pantyhose away with a razor blade.
the mesh size takes some experimenting. i haven't found a mesh yet that is the perfect size. for most pantyhose i find if you just stretch it ever so slightly that is the right size. but it takes some experimentation. i've also tried cheese cloth, and the net from a breeder box i cannibalized. both of those were too large. basically you want the holes in the mesh just barely big enough for newly hatched brine shrimp to be able to slip through, but not so large that they all escape at once. sometimes using a double layer of the pantyhose helps.
i took the extra step of zip tying some old powerhead magnets to the rigid airline tubing to help keep the rig upright in the water, but you could just as easily glue a heavy rock to the bottom of the plastic container, or just wedge it against something.
then take your newly hatched brine shrimp, pour them in to the funnel, and then add just enough water to flush them down in to the container at the bottom.
easy peasy.
it can be helpful if you cover, bury, or otherwise block the light from the sides of the container. brine shrimp tend to swim towards lights, so blacking out the side of your container helps because then the only light coming in will be through the mesh top, which will help encourage them to swim upwards.
