Materials
- One 2-liter bottle
- Bottle Biology Tool Kit (link to tool kit)
- Three to five film cans
- One plastic lid to fit inside base
- Small amount of banana or other fruit
Step 1 – Remove
label from 2-liter bottle.
Step 3 – Poke
a 3-4 mm hole in cap, just big enough for one fruit fly to pass
through at a time. Invert top into cylinder.

Step 4 – Tape top securely so no
flies escape. Place 2-3 slices of banana into 1 film can to start,
and set in bottle base. Set the film can on a plastic lid, like
that from a cottage cheese or deli container, so it doesn't tip.
Once you have caught a few flies, add more film cans loaded with
fruit.
