Harry and Cassie wanted to conduct an experiment to see how many licks it takes to get to the center of a tootsie roll pop. Below is their procedure and above are the results.
1. Obtain test subject.
2. Obtain unwrapped tootsie roll pop.
3. Test subject places tootsie roll pop in center of tongue and drags it to the tip. This is considered one lick.
4. Test subject swallows.
5. Before licking again, the test subject rotates the tootsie roll pop slightly with each new lick to make sure that the entire pop obtains adequate licking surface area.
6. Test subject licks while keeping track of all licks until the tootsie roll is encountered.
What is wrong with this experiment?
A) They should use two different types of candy.
B) There is nothing wrong with the experiment; it was flawless.
C) Based on the experiment procedure, it can never be replicated.
D) The data is not reliable because there was not any repetition.
Answers
Tootsie Pops, which first aired in 1969, a little boy famously poses a tough question: "How many licks does it take to get to the Tootsie Roll center of a Tootsie Pop?"
The inquiry stumps a cow, a fox and a turtle, but the aforementioned bird claims that the answer is three.
While the ad concludes that "the world may never know" the magic number, a new study published in the Journal of Fluid Mechanics has arrived at an estimate.
Researchers at New York University and Florida State University have investigated the "complex process by which materials are shaped and ultimately dissolved by surrounding water currents," according to a pressrelease.
After developing a theory for how flowing water causes dissolving and shrinking, the scientists concluded that it takes about 1,000 licks to get to the center of an average lollipop.
And Tootsie Pops? Doctoral student Jinzi Huang told the New York Post that the number is closer to 2,500.
And just like that, the age-old question is solved.
