Kitchen gadget maker SodaStream is recalling 51,000 bottles because of a risk that they may explode.
The Consumer Product Safety Commission said Tuesday that thousands of SodaStream’s carbonated bottles “can burst under pressure, posing an injury hazard to the user or bystanders.” No one has yet been injured, according to the recall notice.
