Aerator - wine etc
by jawkins, published
The idea is to aerate wines or spirits whilst pouring into the glass using the Bernoulli principle to draw the air in. It is along the lines of the many commercial aerators available.. Not sure if it makes much of a difference, especially after many glasses of wine, but fun trying it out!
I printed with top (big end) down, and it didn't need much support, but should work both ways. The original is a little small, but good for spirits. For red wine, suggest scaling up by around 20%.
