The TikTok trend could pose potential dangers to children.
“Glass fruit,” or tangfleur, is a crunchy sugar topping made from a variety of fruits and has become increasingly popular on social media.
To make tanh hu ru, you need to heat a mixture of sugar and water in the microwave in 30-second intervals for about five minutes until it boils, according to TikTok users Jasmine and Tea, who posted a tutorial in April.

In the video, which now has nearly 20 million views, the food content creator warned that the mixture would become “very hot” and should not be touched with bare hands.

The outbreak has even led to children being sent to hospital while trying out recipes at home.
In August, Shriners Hospitals for Children in Boston issued a notice announcing an increase in cases of children suffering severe burns from sugar spills.
Shriners surgeon Dr. Colleen Ryan reported treating two patients within a two-week period who were injured during the operation.

“When sugar is melted in a microwave like this, it develops a high heat capacity and stores thermal energy,” she said in a statement.
“Spills can cause severe burns, like spilling hot soup, but the properties of sugar can cause deeper burns. When children or teens grab pots or bowls quickly, hot liquids can splash, spill or splash.”

The result, “often results in one or more small but very deep burns in critical areas such as the hands or face,” Ryan said.
“Parents should make sure their children are learning proper cooking safety and take precautions.”
The surgeon said his colleagues in the U.S. and abroad have also reported an increase in such injuries linked to the cooking epidemic.

She urged parents to be aware that their children may come across the trend on social media.
“Children baking their own sweets may seem like a fun, harmless activity,” she says, “but if everyone is aware of the risks, we have a chance to prevent these injuries.”

“Parents need to be vigilant and make sure their children are learning proper cooking safety and taking precautions.”
Dr. Mark Siegel, a Fox News senior medical analyst and clinical professor of medicine at New York University Langone Medical Center, warned Fox News Digital that melted sugar is “dangerous” and how “contagious” this type of viral outbreak could be among children.


“Parents should err on the side of caution, make sure their children are learning proper cooking safety, and take precautions,” warned Shriners Hospitals for Children in Boston. (iStock)
If a child is burned, doctors advise parents to remove clothing from the burned area and wash it with cold water.

The Shriners urge people not to apply ice to burns and to seek medical attention if necessary.
“Blisters are second-degree burns and burn cream may help, but leathery (black, brown, or white) burns may be third-degree burns and should be evaluated immediately,” Siegel added.
