This is cooler than the Mini Claymore by far!
I built one of these at home last night and got some pretty good results. The pencils could have used something to stabilize them in flight, fins or maybe something to give it a bit of spin. Other than that I was able to shoot them across the room with ease. This might be the perfect thing to deter the pigeons from eating the cat food…
