An influencer suffered second-degree burns after trying to make coffee in her Stanley mug.
Larissa Carvalho, from Sao Paulo, Brazil, recounted the painful experience in a series of videos that have reached millions of viewers online in an attempt to warn others.
The 22-year-old explained that she tried to brew coffee directly into the popular thermal mug for convenience, but was shocked to see an explosion of boiling water.
She recalls: “As soon as the water hit my skin, a blister formed and burst instantly.”
The incident allegedly occurred on February 25, when she was with her boyfriend at a property in the coastal town of Guarujá.

The burn was classified as second degree at the hospital and has left a scar on his hand.
The couple was preparing to go to a soccer game when the accident occurred. Larissa said: ‘I hurriedly went to make coffee and put the kettle on the stove to heat the water.
“Then I took the filter, one of those traditional Brazilian plastic ones, and placed it on top of the Stanley glass.”
The digital creator said she used a small cup from the brand and that it remained intact after the accident.
She explained: “A while passed and then there was an explosion with water, coffee, everything flying.”
Stanley water bottles have grown in popularity over the past year, garnering 50 million views on TikTok.
According to Larissa, the water hit several parts of her body, but only burned her arm. She said: ‘The skin bubbled instantly.
“My immediate reaction was to think it was nothing serious until I realized that the pain was unbearable and would not subside.”
After asking her partner who was at home for help, the young woman decided to put the wound under the tap.
However, she saw no improvement and her partner urged her to seek medical assistance. The couple then headed to a hospital, where her injury was reportedly classified as a second-degree burn.
The couple was preparing to go to a soccer game when it happened and Larissa’s boyfriend took her to the hospital.
Larissa said that as soon as the water hit her skin, it formed a blister that “exploded instantly.”
A second degree injury affects the outer and underlying layers of the skin.
The digital creator said she used a small cup from the brand and that it remained intact after the accident.
A chemical engineer said the burn could have been caused by wear on the cup or a defect in its manufacturing. In the photo: left, the burn when it occurred, right, in its healing stages.

She said: “The time between being at home to getting to hospital and getting the medication was horrible.”
After the episode, Larissa Carvalho made several videos recounting the incident.
Dermatologist Geisa Costa explained that burns are classified into three degrees, depending on the severity of the injury and the depth of tissue damage.
Characterized by redness, pain, and swelling, first-degree burns affect only the outer layer of skin, called the epidermis.
Meanwhile, a second-degree injury affects the outer and underlying layers of the skin. The specialist explained: ‘It can cause blisters, intense redness, pain and swelling.’
Third-degree burns affect all layers of the skin and can cause damage to nerves, muscles and bones, the doctor added.
Larissa reported the incident to Stanley, but stated that she received no response, adding that she believed it was just an accident.
Elio Lopes Santos, a chemical engineer specialized in industrial and occupational safety, explained what could have caused the explosion.
He said the problem could have been caused by wear on the cup or a defect in its manufacturing.
However, the accident could have occurred due to a phenomenon.
Santos said: “It is possible that he poured coffee powder over the water, forming a plug.” The water boiled and formed steam, which was expelled suddenly, as if it were the opening of a champagne. This phenomenon is called “boiling.”
In a statement, Stanley confirmed that he was contacted by the consumer and attempted to contact her twice, by email and phone, but received no response.
However, the brand said it will continue to seek feedback and is available to the customer.
Stanley said: “The product used is part of the bar line and can be used with hot drinks, but it is not recommended to brew coffee directly into it, as was done, as it was not designed to be used in this way.”
