Summary

The video discusses an experiment involving aluminum cans and hydrochloric acid. The host begins by mentioning a video from the Nerd Region Chemistry Channel, which performs a dangerous experiment involving an aluminum can and hydrochloric acid. The host is inspired to replicate this experiment, but with a twist: instead of just placing an aluminum can in the acid, he wants to put food in an aluminum can and then put that can in the acid.

The host researches and eventually finds a can of soda that he believes is made of aluminum. However, upon closer inspection, he discovers that the can is actually made of steel. He explains that many cans are made of steel, not aluminum, and they usually have a symbol indicating the material of the can.

The host then decides to perform the experiment with a can of soda, but he realizes that the pressure inside the can is too high due to the carbon dioxide gas. He therefore removes some of the gas to lower the pressure inside the can.

After the preparations, the host pours the hydrochloric acid into the water slowly. A chemical reaction occurs, producing hydrogen gas and aluminum chloride. The host explains that this reaction occurs because hydrogen is produced when hydrochloric acid reacts with aluminum.

The host then discusses the purpose of the plastic layer inside the can. This layer is designed to protect the food inside the can from direct contact with the aluminum. If the food or liquid comes into direct contact with the aluminum, it could react with the aluminum, causing the can to weaken or even pierce.

Finally, the host explains that this experiment was dangerous and should not be performed at home. He promises to make a new batch of soda once the experiment is complete.

Facts

1. The text discusses a video on a channel called "inter habsi" that features a dangerous experiment with a soda can and hydrochloric acid .
2. The experiment involves putting a can of soda, with no liquid, into hydrochloric acid. Over time, a strange reaction occurs inside the can .
3. The presenter asked for suggestions on what to put inside an aluminum can to test the experiment, and received responses from Twitter users, including mothers .
4. The responses suggested various food items in aluminum cans, such as chocolate powdered milk, condensed milk, and sardines .
5. However, it was discovered that these cans are actually made of steel, not aluminum .
6. The presenter then conducted the experiment with a can of soda and a can of food sold in aluminum, but the results were not visible .
7. The presenter also conducted the experiment with a can of tuna and a plastic mass, but the results were not visible .
8. The presenter then conducted the experiment with a can of soda and a can of food sold in aluminum. The aluminum was in contact with the acid, and the pressure was taken off these cans .
9. The presenter then diluted the hydrochloric acid with water and slowly added it to the cans. A chemical reaction had already started .
10. The presenter observed that small balls were coming out of the aluminum where the reaction occurred. The reaction produced hydrogen gas and a compound called aluminum chloride .
11. The presenter explained that although hydrogen could be used to make hydrogen cars, it is not economical because aluminum is an extremely expensive metal to produce .
12. The presenter then conducted the experiment again, this time with a can of soda and a can of food sold in aluminum. The cans were left in the water and after a few days, the presenter was able to remove the acid .
13. The presenter concluded that the plastic inside the cans is used to protect the food from the aluminum .
