I was going to post about bottle rockets.We found out by accident at my family cottage in MI during my younger days.Although my neighbor was upset he wasnt going to have fresh goose year round afterwards(he used to shoot them with a high powered pellet gun ).If you have a stubborn one try the Saturn missiles we had a nickname for them that isn't appropriate but basically they are 96 moon whistlers minus the stick in one shot smile Wait for the geese and enjoy wink
