Hy mates, My son wanted to build this TNT canon: Looking at the TUTORIAL, it seemed simple. But when we activate the dispenser, the first piston pushes the slime block above the dispenser, and when it retracts, it pulls the dispenser with it, which slides over the repeater and breaks it. What did I miss that explains why the slime block pulls the dispenser? Thanks in advance for the explanation.
