11 students suffered an accident during a science lab experiment in a primary school classroom in Sydney, Australia. News Nine reported that at least two students were taken to hospital by ambulance with serious burns.

Initial reports said the experiment involved sodium bicarbonate and methylated spirits, the BBC reported. Helicopters, paramedics and fire trucks rushed to the scene after the accident.

The incident happened at Manly West Public School at 2pm local time on Monday.

New South Wales Ambulance Acting Superintendent Phil Templeman said the wind affected the test and blew around some of the chemicals used.

The Sydney Morning Herald (SMH) said the injured children were believed to be 10-11 years old. According to reports, their bodies including face, chest, abdomen and legs were burnt.

A teacher who was injured in the accident was also treated.

Several parents who were out of school Monday afternoon said they had questions about why the test took place, but added that the incident was under control.

Mitch Ashton, a parent at the school, told the BBC: ‘We heard online that the incident had happened, it was a bit worrying but everything seems to have been brought under control very quickly.’

Another parent, who did not want to be named, said it was a ‘routine science experiment’. The teacher under whom the test was conducted was also very popular.

A resident told SMH that a teacher from the school had earlier come to speak to a group of people who had gathered outside.

The test was a popular school science test available online. The test is done using carbon sugar snake, methylated spirits and baking soda, also known as sodium bicarbonate. The test is basically done by mixing sugar with baking soda, placing a small amount of the mixture on sand moistened with methylated spirit, and igniting the concussion. However, it was not immediately clear what kind of tests the school conducted.
