& shy; Orange juice drink drip balloon, will not burst & shy; Online News, April 13 (reporter Li Yi/Wenlin Dan/Picture) “Don’t let your child play with balloons while drinking orange juice”. Recently, such a online post was posted on WeChat, weibo heat dissipation. According to the website post, orange juice, especially the juice just squeezed from fresh oranges, contains acidic substances, which will corrode the balloon and cause the balloon to explode instantly. This aroused the discussion among netizens: “Orange juice and balloons are common things in daily life. Do they really produce chemical reactions?” & shy; In order to identify whether the website post is true or not, yesterday, Haidu reporter specially conducted experiments and interviewed many experts and teachers to explore the reasons. & shy; Test materials: fresh oranges, lemon, bottled orange juice drinks, bottled carbonated drinks, balloons of various colors, disposable paper cups (used to place fixed balloons), fruit knife. & shy; Test preparation: four balloons of different colors are blown to the same size and placed on disposable paper cups, corresponding to orange, lemon, orange juice drinks and carbonated drinks respectively. & shy; Test 1 fresh juice makes balloon explosion orange juice drink ineffective & shy; Drinks: take several drops of orange juice drinks and carbonated drinks and drop them on the balloon, but the balloon has not changed. The reporter plus-sized the dosage of the drink and poured it in different positions of the balloon. One minute passed, but there was still no response. It can be seen that orange juice drinks and carbonated drinks will not “detonate” balloons. & shy; Fresh juice: squeeze by hand and drop fresh orange juice and lemon juice into the balloon respectively. In the first few seconds, the balloon did not explode. It took more than ten seconds for the balloon to sudden burst. & shy; Test 2 peel Juice instantly detonates fruit nutrient broth with delay & shy; Although fresh orange juice and lemon juice can cause balloon explosion, there is no “instant explosion” as mentioned in the post, but a delay of nearly 10 seconds. Why is this? The reporter started the second group of experiments, taking out fresh oranges and cutting off a complete Peel to expose the pulp of oranges completely. & shy; Fruit nutrient broth: The reporter squeezed out the orange fruit nutrient broth and dropped it on the balloon. The result was similar to the first group of experiments. The balloon exploded more than ten seconds later. & shy; Peel Juice: The reporter squeezed out the peel Juice and dropped it on the balloon carefully. The result was surprising. The balloon was “detonated” almost at the moment of touching the peel Juice “. & shy; Hand contaminated with juice: according to the online post, the hand that has just peeled the Orange will also cause the balloon to explode because it is contaminated with juice. Yesterday, the reporter squeezed out the peel Juice, covered his palm, and then touched the balloon with his palm, but there was no explosion. & shy; Discovery: soluble rubber containing aromatic hydrocarbons in Peel & shy; “not only oranges and lemon, but also the peel Juice of other citrus fruits, such as grapefruit, may cause balloon explosion.” Yang Gong, lecturer in materials science of Liaoning University, said that the skin of citrus fruits is covered with small bumps, among which the ingredients are flavonoids, citric acid and aromatic hydrocarbons. “aromatic hydrocarbons have strong solubility in rubber, it will make the latex layer of the balloon thinner and break.” & shy; Why is the explosion effect of Peel juice and fruit nutrient broth different? Kang Huajing, a teacher of the Department of gardening in Wenzhou Vocational College of Science and Technology, analyzed that the pulp contains saccharides, acids and some vitamins. The concentration of acids is relatively low and the balloon dissolves slowly. “The concentration in orange juice drinks is lower, so it doesn’t work at all.” & shy; In addition, due to the strong volatility of aromatic hydrocarbon compounds, it is likely to volatilize when squeezing it out and smearing it on your hands. Then touch the balloon again, because the concentration is not enough, there will be no chemical reaction. & shy; Reminder: keep away from citrus fruits when playing balloons & shy; In recent years, the explosion of citrus fruit juice in balloons has occurred from time to time. In August, 2014, when a woman in Hangzhou peeled an orange for her child, the juice splashed out. The balloon in the child’s hand sudden burst and a piece of rubber piece flew into the child’s throat, which almost caused the child to suffocate. In addition, balloons purchased on the street are usually filled with hydrogen. Once they explode and encounter fire sources, the consequences are unimaginable. & shy; The experiment of Haidu reporter and the analysis of experts proved that fruits such as oranges and lemon may indeed cause balloon explosion. Experts remind that in addition to citrus fruits, high-alcohol spirit also contains aromatic hydrocarbon compounds, which can also “detonate” balloons. When children play with balloons, parents must take care of them. & shy; Fresh orange juice drop balloon, exploded a few seconds later & shy; Orange peel juice drop balloon, instantly exploded & shy; Preparation of test materials.
