You need to use at least a 1/4" acrylic piece, this will give the baffle some rigid form and use aquarium silicone.
You basically want to have the acrylic to be sandwiched between two beads of silicone, so that it stays in place. The silicone will not "stick" to the acrylic properly.

That being said, why not just get glass baffles?
