1. yes chemicals are not light sensitive, not for this at least don't worry about it, You will need two receptacles (1 gal clorox containers are fine), a cone (you can use paper)... to pour the chemicals in and shake... doing this the day before would be best. Any size is best... stick with plastic... since you are doing this for a short time... try your dollar store for cheap trays, that you can throw away after using this... (four) the bigger the better, you can process more prints at a time.

2.That is a good paper for your purpose.... i suggest looking at ebay for a cheap safelight that you can put in your lamp/light socket... LED's might be fine, although they might fog your image (make it have a gray tone overall)... i think for this purpose the LED's might be fine, try to look one in the correct spectrum if not,you'll probably be fine.

3 unless your buying ready made pinholes.... the difference of the size... even in .0xx mm makes a difference, although a general exposure of 10-30 seconds is fine, testing each one before hand would be best, but time consuming. you can have the kids test one, but it might take to long, although a quick development will be fine.

4 Developing process

4 trays... 2 for chemicals, 2 for water. the biggest you can fit.
latex gloves
clips/hangers, or somewhere to put prints to dry. lean against a sink wall, etc.


1. You will place the sheet in dektol, no need for prewash (gloves will do for the whole process). 2-3 minutes, maybe 1.5 per print...
2. Wash in water for at least 3 min
3. put in fixer for at least 2 min (no longer for rc)
4 wash in water for 5 minutes after you put in the last print (dump out at least 3 times)
5 no need to squeegee they will drip dry quickly enough, you can even dry them outside.

You don't need archival quality for this, and rc paper washes way faster than fiber paper.

5... just place your used chemicals in the same bottles from which you mixed them in (1 gal clorox containers mentioned before).


suggestions

i suggest you get the kids in 5 groups of 5...

safelight on

that means you get the 5 'negatives' and put them in dektol at the same time... but first dunk one in then the other consecutively , (with gloves on of course)... and move them around with your gloves on... then... after 2 minutes... move them over to the water wash (seriously, don't waste time on stop/acid wash)... leave them in for 2 minutes moving them around, again with your glove on.... then, switch them over to the fixer. once out of the fixer, you need to wash them for 5 minutes in water...

keep your paper in the black bag, and in the box at all times. when you are ready to make the positives. you place the paper under the negative as mentioned, and then expose... then put that in the box, get another paper out of the safebag, and reclose lid... again under the negative, and into the box (not the black bag) close lid, etc say for the five in the group. then take all these five prints, and develop them together, as above. You will have to do this five times (around)... remember to be very careful with your paper, and only use it under the red/safelight.

good luck.
