- Bottle: Can be any plastic bottle on earth
- Tube: I used the handle of dish sponge thingy that was about to be thrown out. Any plastic tube is fine.
- Media: Gravel, sponges, floss, ceramics, LEGOs, diamonds, etc. It's all good.
- Air Stone: Should fit inside the tube.
- Air Tubing
- Air Pump
- Check Valve: Optional (but not really)
- Saw (Hack- or other variety. I used a bread knife.)
- Hobby knife
Step 1: Prep the Lid
1. It's study
2. It has a relatively large capacity (1 liter)
3. It has a wide mouth for easy servicing.
The first step is to prep the lid for drilling. The lid comes with a swivel connector on the top that keeps it attached to the neck of the bottle. Luckily this snapped right off with a light tug; I'm not sure if this was due to the bottle's age or if the connection is just flimsy. Still, I definitely expected it to put up more of a fight.
