Since the rhetorical question, "How many licks does it take to get to the Tootsie Roll center of a Tootsie Pop?" was asked in 1970, billions of people have tried. Confess, you and your friends probably tried. As it turns out, there seems to be no correct answer. Even the Tootsie Pop people don't know, despite a few scientific studies.
I've started my own study to answer the question, "How many drinks does it take to empty a beer?" Actually, I am interested in finding out the average volume of a normal drink of beer.
Feel free to join in and report your own data. Just obey the following experiment guidelines:
1) The drink must be a "normal-sized" drink. No gulps or sips. Resist the temptation to drink the remaining liquid in the glass in one large gulp.
2) The liquid ideally should be beer. Although, any carbonated beverage would do.
3) The beer must be drunk from a standard pint glass. Not a bottle or can (Consumption from a bottle or can could be a separate study). A 400 or 500 mL beaker also works nicely (I have a set at home).
4) Drink a standard 355 mL (12 oz) sample and count the number of drinks. Then calculate the average. Repeat as necessary to obtain meaningful results.
My results from last night: 8 drinks per 355 mL, repeated in triplicate (just like any good quantitative analytical analysis). My average swallow volume is 44 mL (1.5 ounces). I am going to repeat the experiment tonight, but I am going to increase my container volume to 709 mL (24 ounces).
According to: Nilsson et. al., the average swallow volume of a healthy adult is about 25.6 mL. If my swallow volume is indeed 44 mL, I am way above average.
The study continues.....
In a second experiment, I consumed 710 mL (24 fl oz) from one container. It required 17 swallows to do so. The average volume was 42 mL. This is very close to the results from experiment #1.
