			Disposal of Acid:
			People that etch a lot of board tend to save up acid then make a larger disposal.
			There are places that will dispose of acid - here is one:

			===Equipment & Supplies Needed for the Workshop===

			Maker sure you have the following:
			# A working laser printer with good toner for printing image onto transfer paper.
			# A computer for running the laser printer.
			# PCB design artwork ready to be printed (and has been tested).
			# Plenty of blue painters tape for securing paper to boards and paper to paper.
			# Sufficient amount of toner transfer paper for class. Have extra for mistakes.
			# Working laminator and clothes iron for applying heat during transfer process.
			# A way to cut copper to correct size (shear(s) or table saw can work, have it ready in advance).
			# Cleaning supplies to prepare copper; dish soap, sponge, paper towels, steel wool, fine-grit sandpaper (take your pick).
			# Containers for soaking boards after toner transfer is complete (small tupperwares work well for this).
			# Ferric chloride acid for etching boards.
			# Nitrile gloves for handling acid.
			# Sandwich bags for acid and copper (2 for each etch - double bag).
			# Container for acid desposal or funnell for putting acid back in original container (depending on depletion).
			# Correct size drill bits for hole drilling of PCB and fits available drill press.
			# Marker or other item for fixing broken traces.

			==== Topics ====
			# Overview of the process including alternatives
			# Copper clad variations and acid options (including disposal)
			# Transfer sheet and transfer method options
			# Hands on making!

			=== Steps ===
			# Print design on paper and mock the board layout to make sure the print is scaled correctly and the mirroring is correct.
			# Cut transfer paper about an inch oversized and tape it to the original print. Print again on the glossy side of the paper.
			# Cut copper clad to approximate size - about an inch over sized again.
			# Using painters tape, tape 1 or 2 edges of the transfer to the copper.
			# Run through the laminator 5 - 10 times (until you're tired of doing it)
			# Soak copper and transfer in water for a couple of minutes, then peel off the transfer.
			# Use 2 sandwich bags and etch the board with ferric chloride
			# Drill the holes using drill press or dremel press.
			# Solder, Test, and Done!
