The little girl imitated the short video and made her own popcorn with cans. Can popcorn made from canned food be eaten?

The components of cans are mainly aluminum alloy (lighter cans for canned beer and coke) and tinplate (heavier cans for Wangzi milk), and then the surface of cans in contact with food will be coated with an inert substance, which can prevent the contents from chemically reacting with cans or the metal elements in cans from dissolving out and migrating to food, but this is generally limited to normal temperature or high temperature.

Like the popcorn operation in the short video, the temperature should exceed 150-200 degrees. It is uncertain whether the inner coating will be damaged at such a high temperature, but it should be risky. This practice is very unsafe, especially easy to burn, but this is the second. The most important thing is that the surface of cans is painted, which may decompose various toxic and harmful gases after heating. Moreover, heating was not considered at the beginning of the design of cans, and the melting point of aluminum is also low, which also has the risk of melting.

It's easy to make your own popcorn at home now. You can do it directly in the pot. Why do you need to find a jar? Extremely dangerous, possibly toxic, and it takes a lot of time. It can only be exploded one by one, just for freshness. As the news said, it is not worth the loss to get into danger because of a moment of curiosity, so I personally think that some operations are just looking, so don't imitate them at will, because there may be some potential dangers that we haven't discovered, so don't always wait until something happens to know regret and fear.
