How do you prevent adjacent blocks from sticking together in game?

I am restarting with Roblox development after a long time away. I am attempting to create a simple pillar consisting of individual blocks, which can be knocked down by the player (with each brick responding independently to physics).

When I stack a bunch of blocks on each other, though (by copying/pasting a bunch of times), they create a solid pillar that moves as one unit in game. I am guessing that Roblox Studio is assuming my intent and reacting accordingly but I’m not sure. I thought that disabling “Join Surfaces” on these blocks would be exactly what I needed but it had no effect. If I space the blocks apart slightly, they act independently, but I’d rather not need to do that.

Is there a way to make these bricks behave independently?

try checking the surface welds property of the parts or check it’s children that has an instanced weld in it when you dont realise it was there before so delete it

Ah, thank you! Because the parts were created with the Join Surfaces option on, every copy/paste created the weld which doesn’t go away when I unselected Join Surfaces afterward. That was the trick!
