SPAN Silicone Dishwasher Net. We’re pretty sure the dude who invented the dishwasher didn’t have kids. Because if he did, he would have found a way to keep plastic bowls and cups from flipping over and filling with nasty water. That’s where we come in. SPAN is a stretchy silicone net that hooks to your dishwasher rack and keeps everything locked down. Duh. Problem solved.
