I bet this guy is one of those guys that has tried everything against these pesky squirrels. I like squirrels and all, but some of them will eat all your plants and get into any food left for birds, everything. You can't really shoot them, well I guess you could, but still, this catapult will make the squirrels think twice before returning. THough they will probably be back sooner rather than later, after they shake off the launch across the yard!
