My Instructable is called vortex because when you flip it and spin it it will make a vortex that will help the water flow down.
Step 1: Materials
The materials you will need to make this Instructable is clear rap duct tape and two lager water bottles.
Step 2: Construction
You will need two large water bottles I got mine at my local 711.
Step 3: Final Step
The Final Step you rap the clear rap around the two mouth holes on the water bottles you my want to layer it a couples times. Then you duct-tape the clear rap you can add sparkles or glitter.
This is how my vortex works I learned how to make this a long time ago when I was a little kid.
