Sticky physics of joy: On the dissolution of spherical candies
Assuming a constant mass-decrease per unit-surface and -time we provide a
very simplistic model for the dissolution process of spherical candies. The aim
is to investigate the quantitative behavior of the dissolution process
throughout the act of eating the candy. In our model we do not take any
microscopic mechanism of the dissolution process into account, but rather
provide an estimate which is based on easy-to-follow calculations. Having
obtained a description based on this calculation, we confirm the assumed
behavior by providing experimental data of the dissolution process. Besides a
deviation from our prediction caused by the production process of the candies
below a diameter of 2 mm, we find good agreement with our model-based
expectations. Serious questions on the optimal strategy of enjoying a candy
will be addressed, like whether it is wise to split the candy by breaking it
with the teeth or not
