2. put a piece of tape over both holes.
3. Take a graduated cylinder and spoon in fruit fly media. Measure out 15 mL.
4. Pour the 15 mL of fruit fly media into a clean plastic vial.
5. repeat 3 times
6. take the same graduated cylinder and fill it with 14 mL of water.
7. take the blue food coloring and drop in 1 mL.
8. Wait for the food coloring and the water to mix, making the mixture a very dark blue.
9. pour the blue mixture into the same vial with the fruit fly media.
10. repeat 3 times, pouring the mixture over the vials with the fruit fly media.
11. Add about 3-5 grains of yeast on top of the mixture, which has now become Drosophila medium.
