F1 Stiki Method Pellets have been treated with a special binding agent that when it comes into contact with water activates and causes the pellets to stick to each other and the Method Feeder. Because of the small amount of water required to activate them it means the pellets stay quite hard so they can be compacted onto a Method Feeder easily and you can be sure that they will stay on through the cast but as soon as they hit the bottom they will start breaking away from the feeder.
