Help me decipher these instructions especially steps 2 and 3?

Question

1. Using the black paper, cut out the shape of your flashlight/torch face (area that the light comes out).

2. Cut a small slit in the middle of the black paper cover which you have just cut out.

3. Place the black paper cover over your flashlight/torch and secure it with tape.

4. Fill the plastic box half way with water.

5. Stand the mirror in the water so it leans against the end of the box at an angle..

6. Point your torch so the light beam shines on the mirror through the water (the flashlight/torch should be on the outside of the container and not submerged in the water).

7. Hold up the white card so reflected light coming from the mirror can shine on it.

I get most of this except steps 2 and 3 hard without pictures. thanks again.

Answer 1

In the center of the circle of black paper you've cut out, cut a one inch (2 cm) long slit in one direction. (Think of taking a knife and just pushing it through the center of the circle so that you have a small slit in the paper.)

Cover the light on your flashlight with this piece of paper and use tape to keep it in place. You want to cover the entire light so that the only light that shines through the black paper, is the light coming through the slit you cut in the center of the paper.

Answer 2

I think the purpose of the paper is to make a smaller beam of light instead of just a big flood of light.  Maybe this will help....http://www.nationalgeographic.com/ngkids...
