Vortex Tube
- Use with your 2 liter pop bottles.
- Give it a whirl and watch a tornadic vortex develop.
The swirling water creates higher pressure around the outer edge
and lower pressure in the center. Air from the bottom bottle
can then travel through the vortex into the upper bottle
allowing the water to move down. Outer winds in a real
tornado spiral upward and inner winds move down through
the vortex.
