Baby bottles are great 8 oz. graduates, 16 oz. measure cups are good for, well, 16.0z. 5X7 trays can be had at the $1 Store...any plastic food storage contaner of the correct size works. Electronic fever thermometers are good for color work, Freestyle has a $5 B&W thermometer. Focth has good bottles. I use wooden clothes pins (turned around in the spring, so the skinny ends close together) for tongs.
