Why do popsicles melt fast

But this softening brings up another factor I just thought of. If the ice-cream softens and changes shape then it could begin to flatten and increase its exposed surface area.

That could be a big factor. Id suggest doing the experiment with identical shapes unconstrained to allow for this factor of softening ice-cream to flatten as it goes and increase area and hence melting AND doing the experiment eliminating this factor by putting them in identical cups. The difference might alter which of the two melts faster.

For the cups it will, counterintuitively, be the popsicle that becomes all liquid first. For the blobs, it will probably be the ice-cream because the flattening as it softens will increase surface area so much that any differences in thermal material properties will not be enough to overcome the faster absorption of heat.

Improve this question. Just be careful to not waste any of the treats. I suggest sitting in your back yard on pleasant summer evenings as the proper place for the experiments. A larger portion has lower surface area to volume ratio, so takes longer to melt.

Pykrete is far from the only fascinating story in the history of frozen treats. The history of ice cream is a tale of creativity and innovation.

Some the most interesting parts are tied to wartime. As the substance was initially too icy, they rigged small propellers to the ammo buckets to churn the ice cream as it flew. The name of the project? Operation Freeze.

Then, in , the U. Later, during the Korean War, the Pentagon made an official statement insisting soldiers got ice cream at least three times a week. Eventually, typically within 15 to 20 minutes, all of the ice cream will have melted and will look like heavy cream. With no air moving, the surface air on the popsicle will be chilled by the coldness of the popsicle surface thus slowing the rate of melting.

If the air, moving or not, is below freezing the popsicle will not melt until it enters the mouth. When energy is added in the form of heat, the water molecules begin to get excited and move around.
