A viral TikTok video has revealed the right way to fill an ice cube tray, and it turns out we've been doing it wrong our entire lives.
American TikTok user "Brittnaenae" shared the 10-second video demonstrating that water should be poured on to the flat spots between the ice cube moulds, according to the Daily Mail.
This allows the water to trickle down into the moulds without splashing or overfilling.
"Am I just dumb? Or did nobody else know this either? These little flat spots on ice cube trays are where you're supposed to fill the water," she says in the video. It's had around 4.3 million views since it was shared earlier this month.
