Eyelash Brush

Eyelashes make great tools when working with insects. Lashes are tapered and strong, firm enough to prod adult insects from a feeding spot and small enough to gently lift a nymph from a leaf.

Materials Needed:
· wooden applicator sticks or 2-3mm x 80mm wooden

- dowel (balsa or other soft wood) (1 per student)

· Exacto knife or razor blade

· eyelash

· tweezers

Instructions:

1) Work in good light and with the help of a partner.

2) Using the knife or razor blade, carefully slit the wooden stick
10mm down, parallel to the shaft center. See figure to the top left.

3) Carefully pull a clean eyelash from your eyelid using your fingers (use eyebrows if eyelashes have cosmetics on them).

4) Hold the wooden dowel with the slit in the upright position
pull the eyelash through the slit by hand or using the tweezers. See figure to the bottom left.

5) Slide the thicker portion of the lash into the slit. The tension of the wood should hold the lash in place.
