My solution for this is to put bread slices all over the place, put the jar of PB into the middle of the room, stick some fireworks into the PB, ignite them, quickly leave the room before the jar blows up. Usually there are 3-4 slices that got splattered with enough PB to eat. Enjoy, but watch for glass splinters!
I don't want to sound gate-keepy, but wait til you have kids. If you can pre-prep something like this during nap time, you can later quickly whip out a couple PBJ's when your kids are screaming for food randomly. Goes right up there with squirtable jelly
Just chunk some goldfish crackers at them if they're that impatient while you spend the half a minute to make it. With my daughter I could usually have the PB spread, the crust cut off, and the sandwich on the plate by the time she was at her table all situated. The video just seems like an insufferable waste of time and fridge space.
