Trainer Motivation

Riding the indoor trainer is far from one of my favorite activities, but maybe there is a way to make it more fun? Maybe with some pipe fittings, an old air compressor, and a few spuds, I could come up with something like this;

Though, I guess while it's still the trainer, I would have to ride it outdoors. Maybe there is a way to run some airlines so I can set the barrel up outdoors to shoot the potato. And there could definitely be some better ergonomics to the design. I mean, you don't want a setup where you need to get off the bike in order to load or shoot it. Especially not during those 30 minute AT efforts.
