So, the main incident appears linked to a Quezon City (Manila area) mall: an indoor waterfall and foam installation suddenly collapsed or leaked, sending a white cascade down several levels, soaking bystanders and disrupting traffic flow.

2. What went wrong?

According to TikTok commentary, a failure—possibly a water leak or malfunction in the foam system—caused the structure to release its contents all at once, flooding walkways and escalator landings below unexpectedly TikTok+1.
