Turn two soda bottles into a working science tool. This coupler lets you screw bottles together, so you can make funnels that pour smooth, hourglasses that flip, or tornado chambers that spin.

The coupler fits standard 2-liter bottle tops. You probably have these bottles at home already. Just print the coupler and you are ready to build. No special parts to buy.

Made from the USA. Get the full OpenSCAD source code with your order so you can print more copies or make changes to the design.
