Wall Breaker water cooler weapon demonstrated
The humble office water cooler bottle is being deployed in the latest military hardware to deal with hostage situations and terrorist threats.
Cardiff-based BCB International has developed the Wall Breaker, a bizarre cannon that fires the water bottles into buildings at high speed.
The firm is already exporting it to military and security forces worldwide.
Business Minister Edwina Hart is touring the company later, marking its 25% rise in sales this year.
Here is the company's video demonstrating the device.
