The video explores the mythically impossible move in Jenga, where removing a single brick from a late-stage game without toppling the tower is deemed impossible. Valerie proposes using a pneumatic actuator to test this myth. Initial tests with supersized blocks fail due to weight issues, leading to adjustments and retesting with standard blocks. The final tests, including a bike and fishing line setup, demonstrate that the impossible Jenga move is indeed possible, with the pneumatic actuator achieving success at 120 PSI.
