I know I can buy these commercially, but would like to make some myself to give to camping friends. Most campgrounds have a fire ring where the camper can build a fire to roast weiners and marshmallows. These commercial pine cones add colors to the flames, like green and blue. How do I make them myself?

I have a bachelorette party this weekend (we are tubing and camping). I want to make a newlywed camping survival kit. They are both very outdoors people. I want to make it kinda silly but I am not sure what to put in it. So far I have one idea which is a bio degradable condom. Please help.

I cant find it online so far, everytime i search it it shows me a black widow. We were camping by the creek and once it got dark there were tons of spiders. They had long skinny hairless legs like daddy long legs but had a fat completly red abdomen. Can someone please help me identify these spiders?
im in arizona, and no. it looked like a daddy long leg but with a fat red abdomen
