Things You'll Need
- Water bottles
- Craft knife
- Duct tape
Instructions
Grab one of the plastic water bottles, and hold firmly on a hard surface where you can hold it steady. The bottle should be lying parallel with the hard surface.
Grasp the craft knife, and cut both ends of the bottle off by cutting evenly along the ridge of the bottle. Trim off any sharp pieces or bumpy ridges.
Repeat the process with the remaining bottles.
Take two of the bottles that you just cut, and fit their ends together so you are making the tube longer.
Hold the two bottles together, and take duct tape around the seam where the two bottle ends meet. This will hold the two bottles together securely.
Add more bottles if you need to make the tube longer, repeating the process for each bottle added.
