Rotterdam

A "mobile rage room," where customers smash things for fun, plans to open next month at ViaPort Rotterdam.

The Riot Room grand opening is April 12 near the pool at the center of the shopping mall.

The concept, according to co-owner Steven Meddaugh, is that people can smash things for fun and to relieve stress. Participants must be over 18.

Participants enter a 16-foot trailer for 10 minutes to break objects like glass cups, ceramics, printers and monitors. The Riot Room provides protective gear, Meddaugh said.
