Mum and son nearly 'drown' in giant ball pit

A still from the video shows an adult helping a child out of the suspended ball pit.

A day of fun out with her son quickly turned into a nightmare for one mum, after she and her child found themselves "drowning" while playing in a giant ball pit.

Vivien Low uploaded a video of the incident to social media, which shows her calling for help after becoming completely submerged in thousands of plastic balls.

The incident occurred at Airzone, a suspended playground in Singapore, which features a massive ball pit containing over 40,000 balls sitting on top of a bouncy net.

Low said she faced her fears of heights because her son wanted to play in the pit, but soon received the "fight of her life" after losing her balance and becoming stuck.

"I could not reach the bottom and I could not stand up. I tried to roll over, I couldn't. I tried to find the net so I could grip it, I couldn't," she wrote on Facebook.

"My son was stuck inside too. I panicked and waved and screamed for help. None came. I seriously panicked and did not know what to do."

She said she eventually grabbed someone's hand and stabilised herself before pulling her son and two other small children from the pit.

The woman has called for a safety review of the play area following the terrifying ordeal.
