relax, you said the silkworms are all tangled in their silk; well first you pick them out one by one and put in another container temporarily. once you do this go to walmart or craft store and get a 12" x4" or so container. also buy plastic canvas(looks like plastic with a bunch of holes in it). cut the plastic canvas to fit directly into the container you bought. take a toilet paper roll and cut a (2) 1/2" slivers of the end, this is what will keep your canvas from laying on the bottom of the container( and thus creating a poop area, so you worms arent crawling around in their own poop). place the half inch circles in the bottom of the container and then put the cut to size canvas on top of the circles.
place your silkies on top of the canvas and your done, except for daily food. like someone said before, take some of the hornworm food and grate over the silkies daily until your food arrives. if you run outa food you can grate carrots over the silkies(temporarily) to keep em alive. and you can always feed more silkies daily to get rid of em, I have fed over 10 a day when i ran outa food.
as far as the hornworms, keep em in their pod and they should be ok, but i wouldnt feed off more than 1 a day or those or you will have some nasty runny poo from your chams.
hope this helps.
