What we do with PVC

Simon and I do everything with PVC from shooting a marble 3 feet to shooting an arrow 100 yards.
Heres a list:
Make bows
shoot marbles
swordfight
make marshmallow guns
make rubber band guns
mess around
We both make whatever we cant get or afford. We also do a lot of things with rubber bands, paperclips, pens and fireworks but that will have to be a different post.
