WashingSacks dissolve with your laundry

Wouldn't it be great if you could just show up to the laundromat with your bag of dirty, filthy laundry (you know
how we do) and throw the whole thing in, lock stock and barrel? Well with WashingSacks you can—they're laundry bags infused with detergent that also dissolve in water. No fuss, no muss. But did they figure out a way to get the laundry back home?
