Dissolving Detergent Ball

As i was lugging the big three litre jug of liquid laundry detergent up a flight of stairs to the laundry area in the apartment building, i was thinking "George, " (because George is what i call myself in my head) "George, wouldn't it be easier if you only had to carry a single-usage unit of laundry detergent, like when you carry a single dryer sheet?" Not surprisingly, i also thought the answer was "Yes".

I propose that liquid laundry detergent could be sold as a box/carton of single-use spheres that is held together by a soluble skin that quickly comes apart and dissolves in water. The skin allows individual units while not resorting to excess wasteful packaging that would wind up in a landfill.

If anybody has ever played paintball, think of a large version of the paintball ammo. (although i have no info on whether they are soluble or not)

I also picture them being blue, because i like blue.

Of course, the downside is that the detergent company gets to determine how much laundry detergent you use on each load. Maybe they could sell different sizes for different needs.
