- [00:00:05.648]Your eyes, hands, hearing.
- [00:00:08.981]Let's say that's a, a damselfly's down there,
- [00:00:11.689]you, that's the technique
- [00:00:13.772](clicks tongue) just scoop and twirl and then
- [00:00:16.368]you just kinda slap 'em down like that.
- [00:00:19.971]We go out and set traps.
- [00:00:23.298]People go out to the field station or doing field work,
- [00:00:27.640]there are these, what we call liquid nitrogen tanks.
- [00:00:31.971]Liquid nitrogen is very cold.
- [00:00:33.601]They drop these vials into the liquid nitrogen.
- [00:00:36.321]It's immediately freezes them.
- [00:00:39.110]I'm gonna use my OptiVISOR
- [00:00:41.350]This is gonna magnify the view
- [00:00:45.821]so I can see a little better.
- [00:00:48.541]My dissecting tools are sorta the important ones.

- [00:01:00.131]Here, you hold your forceps like silverware.
- [00:01:04.540]So these are some of the basic tools
- [00:01:05.883]that I would use to start a DNA extraction.
- [00:01:08.531]This, we call a douncer
- [00:01:09.971]that we use to basically crush a parasite.
- [00:01:13.300]So that just starts the extraction process.
- [00:01:16.192]In order for us to study these things,
- [00:01:19.009]we have to be able to have a good microscope
- [00:01:21.219]to see these structures.
