Doctors have warned parents about a viral TikTok challenge inspired by the Netflix show Squid Game that has resulted in three children being admitted to a Sydney hospital with burns.

The children experienced injuries ranging from scalds to nerve damage, with all three requiring ongoing treatment, after taking part in the trend which involves making honeycomb.

Acting head of the burns unit at The Children’s Hospital at Westmead Dr Erik La Hei said honeycomb could be dangerous because of the high temperature at which sugar melts.

The TikTok trend involves carving a shape into homemade honeycomb without breaking it.
