I was able to do this without the key press by getting rid of the flip flop since it’s not on key press (mainly my test method for enabling and disabling things) and change the key press node to an on actor hit event. You can get this by selecting your soda can, right click in your level BP and set an event for actor hit.
Give that a shot and see if you get the reaction with collision. This is just a basic starting point. Using ray tracing to detect hits of where the can is and changing it’s bounce direction would be the next step if you want it pinging around a room. This will solely be dependent upon the collision capsule and often resulted in it just bouncing once or twice an then the thruster keeping it forced against the wall or floor.
